Details
Web page or screen you were on when you saw the issue: Steps to reproduce: 1. go to this webgl test: https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/demos/google/shiny-teapot/index.html 2. 3. What you expected: A teapot displayed Actual: Crash Crash report ID (if applicable): https://crash-stats.mozilla.com/report/index/bp-deffd20c-dca2-4d2c-9877-5a3172111211 I believe other tests in the suite will cause similar crashes. Need to check more of these tests in this suite.

Shouldn't we group together all those malloc-related crashes triggered by WebGL demos on Android? For all we can see, they're likely all the same bug.
Crash Signature: [@ __atomic_cmpxchg ]
Benoit, I was thinking the same thing. How would you like me to group them? Should I go ahead and dup or do you want me to create a meta bug or do you want me to create a whiteboard tag?

Summary: webgl demos causing repeatable crashes → WebGL demos causing repeatable crashes
I'm testing a patch that makes us revert to using the GLSL backend instead of the ESSL backend in the ANGLE compiler. Shouldn't make a behavior difference anyway, as on ES we're just passing the original shader source to the driver, but could avoid this crash if it's related to the ESSL backend. https://tbpl.mozilla.org/?tree=Try&rev=72ded8c7f176 Builds and logs will be available at http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/bjacob@mozilla.com-72ded8c7f176
We were able to confirm on AaronMT's phone that this patch fixes the crash.
