I just uploaded 98.0.4758.102-1, please let me know if it still happens there.
Also, do you get symbols in the backtrace when you run "chromium -g"?
Hi,
the warning is still present in version 98.0.4758.102-1,
but there is a slight change:
the trap seems to be catched by chromium itself - gdb does not stop on trap
anymore.
