[libcxx-commits] [PATCH] D150897: [runtimes] Use libunwind from libc++ and libc++abi by default

[Manoj Gupta via Phabricator via libcxx-commits]

manojgupta added a comment.

GCC's libgcc_s/libgcc and llvm's libunwind are not ABI compatible, the code will compile/link but will crash at runtime for calls to functions like backtrace() because functions from libunwind and libgcc will get intermingled. So this is a risky change for the users. I'd strongly advise to make a note of this is release notes.
