Alex, Mats, do you see this on Windows or on other platforms, including versions other than Windows 7 32-bit? Which test does it appear to fail on?

Can't reproduce this on Windows 7 or 8.1. The crash is in code that clears out the font cache when the memory pressure event fires so I think the steps to reproduce needs to induce this.

Marking steps-wanted for more detailed steps to reproduce.

Also cc'ing the WebGL guys, just in case.

Alex, have you seen this crash recently? I'm seeing zero reports against the current release and 8 reports against the previous release.

https://crash-stats.mozilla.com/report/list?product=Firefox&signature=gfxFont%3A%3AClearCachedWords%28%29#tab-reports shows a total of 13 crashes on 40.0.2 all the way up to 43.0a2.

Tried yesterday and I can make the current Beta crash on demand with these steps:

- Load https://www.khronos.org/registry/webgl/sdk/tests/webgl-conformance-tests.html
- Click "run tests" button

Will try on Nightly and report back.

¡Hola Anthony!

The Beta crash I mentioned early is https://crash-stats.mozilla.com/report/index/695f5139-51ca-4fef-bdf2-ae8302151011 which is "OOM | small"

Tried on Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:44.0) Gecko/20100101 Firefox/44.0 ID:20151010030234 CSet: d1bb0de19476541cd517ab14017e7fedbd9f13e3 and it does not crash but produces all the errors and timeouts below.

The timeouts seem to be the more troublesome as those cause the OS to mark Nightly "(Not Responding)" yet it left on its own it eventually recovers.

Perhaps the fact that Nightly is 64-bit as opposed to 32-bit Beta shields it from the "OOM | small" crash?

Shall I file separate bugs for said errors and timeouts?

¡Gracias!
Alex

There are also reports with "PLDHashTable::ClearAndPrepareForLength" in the signature
with a similar stack, e.g.  bp-76afd977-2c34-4f8b-87f2-9ac922151006
I think this crash bug has occurred for a very long time.  It would be good if we
could finally fix it now that it seems reproducible at least on Beta (per comment 5).

Even adding all those crashes together I count 24 reports which doesn't even come close to breaking into the top-300 crashes. However that does not account for reports hiding in OOM|small.

These steps do not reproduce for me. If we want to fix this crash I think the next step is getting a developer to debug this with Alex.

No, I don't think so.

I am closing this bug report as it remains unreproducible and there are zero reports of this crash in the last month. Please reopen if you can reproduce this crash.

Yeah, it seems like this is still happening. I'm not sure why it wasn't showing for me earlier. Currently there are 9 reports against 46.0.1 over the last week. Unfortunately there are no strong correlations nor any comments to provide any leads. 

I am dropping the reproducible keyword since earlier comments suggest we don't have reproducible steps to reproduce this crash and current volume suggests this isn't widely reproducible for users either.

Based on the last year of data this goes back to at least Firefox 36. Unfortunately I cannot go back further than a year.
