--- Comment #6 from Kostya Serebryany <kcc at gcc dot gnu.org> --- > How does your GCC behave with the test case? The sanitizer code in GCC is > imported from Clang, I believe, so it probably does not crash either? I get this: ~/gcc-inst/bin/gcc -fsanitize=address -static-libasan d.c && ./a.out AddressSanitizer can not describe address in more detail (wild memory access suspected). Did you check the GCC trunk?
