[cfe-dev] Mac OS X (Darwin) and Symbol not found: __ZTIN10__cxxabiv117__class_type_infoE

[Jean-Daniel Dupas]

You can workaround this issue by disabling the specific undefined behavior check that uses this symbol:

clang -fsanitize=undefined -fno-sanitize=vptr

I just hope Apple will fix the OS X libcxxabi exported symbols in the next release.
