Comment #6 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
Glad I could help :)
For an example, see also https://bugzilla.mozilla.org/show_bug.cgi?id=857189
In particular the last hunk of the patch:
+# ifdef MOZ_ASAN
+// When running with asm.js under AddressSanitizer, we need to explicitely
+// tell AddressSanitizer to allow custom signal handlers because it will
+// otherwise trigger ASan's SIGSEGV handler for the internal SIGSEGVs that
+// asm.js would otherwise handle.
+extern "C" MOZ_ASAN_BLACKLIST
+const char* __asan_default_options() {
+ return "allow_user_segv_handler=1";
+}
+# endif
