--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
I've just verified that clang 3.8.1 emits *_noabort calls with
-fsanitize-recover=all:

$ clang++ -fsanitize=address -fsanitize-recover=all /tmp/leak.c -S ; grep store
leak.s
        callq   __asan_report_store4_noabort

Thus, do we want to change the behavior for GCC 7.1?
