Comment #4 on issue 302 by [email protected]: Add ability to
forward SEGVs to ASAN handler
http://code.google.com/p/address-sanitizer/issues/detail?id=302
I don't fully understand why putting this into ASan would make it
simpler/safer. The way this flag works is the standard way for all C signal
handling, plus it works in the presence of even more signal handlers for
the same signal (e.g. your signal handler, third party signal handler and
ASan signal handler).
And I'm not sure if you're aware of that, but you can make
allow_user_segv_handler=1 the default for your program, by directly
compiling the default options into your program (no ASan modification
required, no ASan flags required at runtime).
