[PATCH] D70910: [compiler-rt] Add a critical section when flushing gcov counters

[JF Bastien via Phabricator via llvm-commits]

jfb added a comment.

When you say "when the process is forked in different threads" you mean threads, not fork, right? Because this won't fix any issues you're seeing with fork.

It's also unclear that this fixes the issue correctly. `flush_fn_head` is accessible from other functions, also unprotected. Can the other functions be invoked while this one is?
