It looks effectively the same (or least similar).
In my case, the offending line was:
# pragma GCC optimize("-fomit-frame-pointer")

When removing this line, the crash disappeared.
I suppose this is the same bug as PR53214 (even if this bug
was with attribute rather than pragma).

Thanks for the help
