[libc-commits] [PATCH] D76676: [libc] Unblock SIGABRT before raising in abort

[Fangrui Song via Phabricator via libc-commits]

MaskRay added inline comments.


================
Comment at: libc/src/stdlib/abort.cpp:34
+  // interrupted by any async signals. The user handler will be run once we
+  // unblock if it was blocked previously.
+  sigset_t set;
----------------
Another thread may concurrently install a signal handler for SIGABRT or unblock SIGABRT. There needs to be a lock.
