search for: __ubsan_handle_float_cast_overflow

Kostya, Christophe, I'm running the full tests on AARch64 and the only RT test that fails is: UndefinedBehaviorSanitizer-Standalone :: TestCases/Float/cast-overflow.cpp The problem seems to be a trap in __sanitizer::internal_memchr() while trying to handle __ubsan::__ubsan_handle_float_cast_overflow(). I haven't looked at it in detail, has anyone seen this? Is UBSan meant to run on AArch64? Should we mark this test XFAIL until it can be looked at properly? cheers, --renato
