Note that I've set the SA_NODEFER flag for the SEGV handler in the ASan runtime only a couple of days ago. Not sure that could've affected this test though; without that flag the second SEGV would've simply crashed the program. But you can try removing the flag from compiler-rt/trunk/lib/sanitizer_common/sanitizer_posix_libcdep.cc and see if that makes any difference. HTH, Alex On

Hi lists, I am encountering a large number of check-clang failures after building Clang/LLVM with -DLLVM_USE_SANITIZER=Address. I have reported the issue on Bugzilla (https://bugs.llvm.org/show_bug.cgi?id=47678). I cannot even compile helloworld.c with the resulting clang tool without a lot of false positives from ASan. Is it because I am not supposed to use GCC's AddressSanitizer when
