Andrew: Can you get someone to help us investigate this new top crash in Beta 9?
Tagged as blocking for Beta50 release.

Hi Kats, Milan, could you please help find an owner who can investigate? We only have one more beta build before we enter RC week and this one is a top crasher on 50.0b9.
Hi Neil, could this be related to the fix we took in b9 for bug 1304243?
This is the beta 8 -> beta 9 changelog: https://hg.mozilla.org/releases/mozilla-beta/pushloghtml?fromchange=FIREFOX_50_0b8_RELEASE&tochange=FIREFOX_50_0b9_RELEASE. Display lists and stacking contexts.

Of the entire pushlog bug 1304243 is the only one that touches anything in layout/, so it does seem like the most likely candidate given the crash stack. Some of the crash report comments seem to indicate the crash is happening on Facebook.

There isn't really anything interesting in that range. This looks a lot like bug 772330. 100% of the crash are from 'AuthenticAMD family 20 model 1' or 'AuthenticAMD family 20 model 2' CPUS. There's no known fix for this, but there's a good chance it will be gone again in the next build.
No reports with 50.0b10 so far.
This signature disappeared in 50.0b10 and 50.0b11, but in 50.0b11 we have `js::HeapSlot::set` with the same correlations to AMD CPUs.

After the initial spike, this crash signature has disappeared from 50.0b10. Removing the blocking tag and marking this as wontfix for 50.

this sees to affect the 52.0esr build at the moment - the signature is 2% of browser crashes there at the moment. Correlations for Firefox Esr (53.13% in signature vs 01.00% overall) CPU Info = AuthenticAMD family 20 model 2 stepping 0 (46.81% in signature vs 00.81% overall) CPU Info = AuthenticAMD family 20 model 1 stepping 0
