bionic/libc.so (__start_thread+64) Crash

[Alex Redston]

Hi fellow webrtc followers

I'm struggling to know where to look, everything seems to point back to the libc.so but I can't really see where this is:

https://cs.android.com/android/platform/superproject/+/master:bionic/

This bug represents 57% of our crashes and is across all architectures. IT has affected every build of WebRTC so far, we are currently on M108 for latest version of our app.
