Runtime error of dcurl running with the undefined behaviour Sanitizer
marktwtn opened this issue · comments
I found out there was a runtime error while I was reading the dcurl log of undefined behaviour Sanitizer in the buildkite CI.
Error message:
/usr/lib/gcc/x86_64-linux-gnu/7/include/emmintrin.h:703:10:
runtime error: load of address 0x560fe0847da4 with insufficient space for an object of type 'char'

It is probably caused by the intrinsic function of trinary_sse42.h.
The default setting of undefined behaviour Sanitizer does not return error value,
hence the error is not detected at the first time.
It can be fixed with the compiler option -fno-sanitize-recover.
