behaviour errors for further debugging purposes or to put it into my
testcases. I want to achieve that saving the active unit during the time
ubsan reported the error.

It is about UBSAN (!) errors. Ubsan reports only and doesn't crash the
process.

For example:
src/pcre2_compile.c:6453:42: runtime error: unsigned integer overflow:
4294967295 + 1 cannot be represented in type 'unsigned int'
SUMMARY: AddressSanitizer: undefined-behavior src/pcre2_compile.c:6453:42
in

I want to save the unit that was running during the error.

Kind regards,

Karl Skomski
