--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 59669 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59669&action=edit gcc15-pr117731.patch Untested fix. We don't develop the sanitizer code inside of GCC and all we care about is whether it builds with GCC, don't need -pedantic to ensure it will build also with other compilers (and it is up to LLVM people to make sure it builds with clang).
