This crash happens when running drawingbuffer-static-canvas-test.html. It seems to crash on context creation, so there's no JS context yet (so I didn't include a backtrace of the JS stack).

This seems to be a regression that appeared somewhere between 2 weeks ago and yesterday.

Removed an assert that seemed to be crashing this test. Without it, this test and the rest of the mochitests run fine.
Attachment #558897 - Flags: review?(matt.woodrow)
I'd like to know more about why this is happening.

That assert should only ever be hit if the requested size is greater than GL's max texture size. WebGL also requires a texture, so how did it manage to allocate a backing buffer of this size?

What is the size being passed in to CanvasLayerOGL::Initialize, and how is the WebGL object handing this size?
(In reply to Matt Woodrow (:mattwoodrow) from comment #2)

The script here tries to create/resize a WebGL canvas of size 64k x 64k. The max texture size on his machine is 16k. For sure WebGL context creation/resizing didn't succeed. Maybe though the WebGLContext code (WebGLContext::SetDimensions) fails to properly report this failure. Can you please have a look at it and tell me if there's something more it should be doing:

http://hg.mozilla.org/mozilla-central/file/2cbb9f7ffe32/content/canvas/src/WebGLContext.cpp#l510

When it fails, it actually doesn't do anything else than return NS_ERROR_FAILURE:

SetDimensions shouldn't modify mWidth/mHeight if context creation fails, so I can't see how thse would ever be set to an invalid size.

Can someone please step through SetDimensions() and GetCanvasLayer() to see how the invalid size gets set, and how we manage to get a valid gl context to pass into layers.

I feel like we should be returning nsnull from GetCanvasLayer() rather than creating a layer that can't draw anything.
I think we figured it today on Mac: GLContext::ResizeOffscreen is virtual and reimplemented in GLContextCGL, so we never do the size check in GLContext::ResizeOffscreenFBO, calling IsOffscreenSizeAllowed...

Need to check all GLContextProvider's for similar issues.

Isn't this fixed already by some recent change?
Yes, I think so. I'll track it down.

Heh, silly me. Past-me correctly marked this as blocked by the same bug I wasted time looking up. :)
