I have an exception that is failing the tests on clang-6/ubuntu18.04 (UBSAN exiting the process), but not on gcc-8/ubuntu18.04 (full log below).
UndefinedBehaviorSanitizer:DEADLYSIGNAL ==8303==ERROR: UndefinedBehaviorSanitizer: FPE on unknown address
This FPE is happening for instance after reading from a null pointer.
I've searched on how to silence/blacklist this, but none of the approaches worked so far, and I am not sure what is provoking this FPE.
Are you setting the environment variable UBSAN_OPTIONS=print_stacktrace=1?
