this crash signature is showing up with increased frequency in the Firefox 70.0.1 release. it seems to be specific to AMD cpus "family 23 model 1" (Ryzen 7), which is the first time for this particular cpu family afaik.

Currently this signature is #14 overall on the 70.0.1 release.

Unfortunately the crash reports don't seem to reveal where the issue is.
The code where the crash is happening hasn't changed recently.

nsThread::ProcessNextEvent has changed a little. Could this be related to some fission work? As a reminder, this issue was reported for the 70 release.
