These are the #2 Mac topcrasher on both the 25 and the 26 branches -- even though they only happen on OS X 10.6.  The crash stacks have no symbols, and are so badly truncated as to be almost useless.  But I'll try to glean what information I can from them.
Crash Signature: [@ libGLImage.dylib@0x234e4] → [@ libGLImage.dylib@0x234e4 ]
Keywords: topcrash-mac
Here's a reconstruction of the top three elements of this bug's crash stacks, using atos and the Hopper disassembler:

void glgConvertTo_32<GLGConverter_ABGR8_ARGB8, (GLGMemory)2>
     (GLGOperation const*, GLDPixelMode const*) (in libGLImage.dylib) + 303
glgProcessPixelsWithProcessor (in libGLImage.dylib) + 2418
glgConvertPixels (in libGLImage.dylib) + 171

I can set breakpoints on any of these in gdb, but for some reason they never get hit (even testing with a bunch of the URLs from comment #0).  Possibly it's because this code only gets exercized with non-default settings.

Benoit, do you have any ideas?
Flags: needinfo?(bgirard)
libGLImage.dylib is in the Libraries subdirectory of the OpenGL framework.  glgConvertPixels can be called from the QuartzCore framework or the QuartzComposer subframework of the Quartz framework.
Even though these happen only on OS X 10.6.8, and so are probably ultimately caused by one or more OS bugs, roughly a third of our users are on SnowLeopard -- so this bug is worth paying attention to.  (Though it may ultimately prove to be intractable.)
I spoke too soon.

Once I switched from running 10.6.8 in a VM to running it on real hardware, I saw *lots* of calls to glgProcessPixelsWithProcessor.  Here's an example.

(In current m-c nightlies these happen on a secondary thread -- the Compositor thread.  But since these crashes appear to start with the 25 branch, I thought it best to get a 25-branch stack.)
Flags: needinfo?(bgirard)
No calls happen to glgProcessPixelsWithProcessor when "Use hardware acceleration when available" is unchecked.  So presumably these don't happen in that case.
These crashes (though with a different signature, and in lower numbers) on OS X 10.7.
Crash Signature: [@ libGLImage.dylib@0x234e4 ] → [@ libGLImage.dylib@0x234e4 ] [@ libGLImage.dylib@0x21f1f ]
Summary: [10.6] Firefox crash in libGLImage.dylib@0x234e4 → [10.6] [10.7] Crashes in glgProcessPixelsWithProcessor
Crash Signature: [@ libGLImage.dylib@0x234e4 ] [@ libGLImage.dylib@0x21f1f ] → [@ libGLImage.dylib@0x234e4 ] [@ libGLImage.dylib@0x21f1f ] [@ libGLImage.dylib@0x2362c ]
These also happen (in still lower numbers) on OS X 10.8.
Crash Signature: [@ libGLImage.dylib@0x234e4 ] [@ libGLImage.dylib@0x21f1f ] [@ libGLImage.dylib@0x2362c ] → [@ libGLImage.dylib@0x234e4 ] [@ libGLImage.dylib@0x21f1f ] [@ libGLImage.dylib@0x2362c ] [@ libGLImage.dylib@0x27aaa ]
Summary: [10.6] [10.7] Crashes in glgProcessPixelsWithProcessor → Crashes in glgProcessPixelsWithProcessor
The number of these crashes on the 27 and 28 branches is vanishingly small.  I wonder why?

Could it have something to do with OMTC (bug 756601)?

OMTC is off for all releases on OS X 10.6 -- though interestingly not for today's m-c nightly.  Benoit, do you know when OMTC started being used in m-c nightlies even on OS X 10.6?

On 10.7 and up, OMTC is on (in FF releases) as of FF 25.  If OMTC is a (beneficial) factor in these crashes, that could explain why there are so many fewer of them on 10.7 and 10.8 than on 10.6.  But the number of crashes on 10.7 and 10.8 (in FF releases 25 and up) is still fairly large -- so I don't think OMTC can be the only factor.

In any case, though, we have reason to hope that using OMTC helps with these crashes.

> Benoit, do you know when OMTC started being used in m-c nightlies even on OS X 10.6?

Never mind, I found the answer:  bug 890997 (which landed on m-c on 2013-10-22).
Flags: needinfo?(bgirard)
These crashes, or something very similar, have also been reported for other programs:

When bug 890977 landed, m-c was on the 27 branch.
> Maybe Bug 670573 resurfacing?

The stack at bug 670573 comment #8 looks a lot like the one I posted here at comment #5.  So bug 670573 may somehow be related.
The crashes on OS X 10.7 and 10.8 all happen on a secondary thread (presumably the compositor thread):

https://crash-stats.mozilla.com/report/list?signature=libGLImage.dylib%400x21f1f
https://crash-stats.mozilla.com/report/list?signature=libGLImage.dylib%400x27aaa

So using OMTC doesn't stop these crashes from happening.

Looking through these crash reports again, they're almost all with NVIDIA graphics (and drivers) -- vendor ID 0x10de.  Here are the particular adapters on which these crashes happen most often:

NVIDIA GeForce 9400M, adapter ID 0x0863, about 30%
NVIDIA GeForce 320M, adapter ID 0x080a, about 30%
NVIDIA GeForce 9400, adapter ID 0x0869, about 10%

And about 10% of the OS X 10.7.5 crashes are on:

NVIDIA GeForce GT 650M, adapter ID 0x0fd5

This the hardware we should be testing on in our attempts to reproduce these crashes.
Marcia, a lot of your URLs from comment #0 are truncated.  Could you do another list, this time making sure they don't get truncated?
Flags: needinfo?(mozillamarcia.knous)
Note that Socorro by default shows URLs in shortened form but there is a "show full URLs" button at the top right of the table.
Right, we upload on the compositor now to prevent blocking the main thread on the upload so that it can start the next repaint faster.

On bug 949573 I'm working on removing the upload and swizzle entirely. This should speed things up and avoid this call all together. Although it wont remove all the code path that may be hitting this function.

Thanks, Marcia, for your non-truncated URLs ... but I wasn't able to get crashes out of any of them.

I tested in FF 25.0.1 (very well represented in our crash stats) on a Retina MacBook Pro with NVIDIA GeForce GT 650M graphics (on its PCIe bus) running OS X 10.7.5.  I used gfxCardStatus (http://gfx.io/) to force apps to always use the "discrete" graphics (i.e. NVIDIA graphics I mentioned above).  I concentrated on the longer URLs (those that don't require an account), hoping that the more specific the information, the more likely I'd be to crash.

I didn't see a single crash.

As I said above in comment #9, there are (currently) hardly any of these crashes on the 27 and 28 (and 29) branches.  As of now, I think our best bet is to wait and see if these numbers increase.  If they don't, these crashes will presumably go away on their own (as the proportion of our users on those branches increases).

This crash is pretty erratic with just 2 reports over the last month against Firefox 26. Going back over 6 months of data the most current version reported is Firefox 46.0.1 on May 26. I am closing this bug as incomplete given how rare this is and the fact that it's not been reported in a current release for several months. 

Please reopen this bug report if you have steps to reproduce this crash in a current version.
