[PATCH] D67298: [ASan] Fix test case dlopen-mixed-c-cxx.c without C++ stdlib

[serge via Phabricator via llvm-commits]

serge-sans-paille added a comment.

Mmmmh the whole point of the test is to test how asan behaves when meeting a symbol like `__cxa_throw` in a dlopened library when the calling compilation unit is not linked against libstdc++. Previous behavior was a segfault, we should now get a reasonable error. By defining `__cxa_throw` in the c file, you remove the origin of the bug, so sure it works, but it no longer tests the faulty situation. Maybe tehre's a symbol defined in both libcxx and libstdc++ the same way?
