[PATCH] D138095: [asan] Keep Itanium mangled names in global metadata

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Reverted it for now. Debugged a bit using @zequanwu's macOS, running a test under lldb said that `free(demangled_name)` in `compiler-rt/lib/sanitizer_common/sanitizer_symbolizer_posix_libcdep.cpp` segfaulted.
This is really puzzling. It's a standard practice to call `free` on `__cxxabiv1::__cxa_demangle` allocated string (`realloc` under the hood). Both realloc/free are intercepted by sanitizers.
