Hi!

I have an "interesting" x86-32 system on thinkpad x60. Depending on
kernel version, chromium either works or fails with floating point
exception.

Working:

Linux amd 5.12.0+ #104 SMP PREEMPT Tue Apr 27 10:31:57 CEST 2021 i686
GNU/Linux

Broken:

Linux amd 5.15.0-rc5-next-20211015+ #204 SMP Sun Oct 17 10:29:18 CEST
2021 i686 GNU/Linux

pavel@amd:~$ chromium --temp-profile
Floating point exception (core dumped)

Is there any chance to get anything useful from the coredump? Besides
bisection, does someone have any ideas?

Best regards,
Pavel
