Yeah, you are right, the change seems to be intrusive. I ran Chromium tests with the patch and hit on -fvisibililty=hidden stuff (we should not export _asan_genXXX symbols for hidden globals), so we should be very careful here. I'm updating the diff.
As for something really big, I thought Android would be a good candidate (AFAIK, Eugeni hit on ODR fiasco there), but I'm not sure I can build and run it without help (at least I don't have a target device). It would be nice if you could help me here somehow.
