Then I believe that your issue is different. In my case, the crash always
happens in mesa code. The last stack frame varies slightly, which is probably
caused by wrong memory reference in the previous stack frame already.

I have attached the most recent backtrace, where the topmost stack frame is
unknown to the debugger, probably because the previous stack frame has already
attempted to use wrong memory address. Not sure.

As of how to debug this properly, I believe that a core dump may be sufficient
for someone familiar with the code. I can provide a lot of them if needed.

If there are too many optimized-out values to properly understand the issue, it
would be necessary to compile some parts without optimizations and try again.
