--- Comment #3 from Kostya Serebryany <kcc at gcc dot gnu.org> 2013-01-15 09:04:35 UTC --- >> False return from these functions will not negatively impact GCC at run time No change in libsanitizer can affect GCC at run time unless you are building something with -fsanitize=address|thread. This particular change will not affect anything but the libsanitizer's own tests. Committed http://llvm.org/viewvc/llvm-project?rev=172523&view=rev upstream. Will port to gcc with the next merge (sometime this week, hopefully).
