-// On Darwin, raise sends a signal to the main thread instead of the current
-// thread. This has the unfortunate effect that assert() and abort() will end up
-// bypassing our crash recovery attempts. We work around this for anything in
-// the same linkage unit by just defining our own versions of the assert handler
-// and abort.
