GCC versions at least 12 through 15 incorrectly report a warning about code in sha1.c:tests/tcg/multiarch/sha1.c:161:13: warning: ‘SHA1Transform’ reading 64 bytes from a region of size 0 [-Wstringop-overread] 161 | SHA1Transform(context->state, &data[i]); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is a piece of stock library code for doing SHA1 which we've simply copied, rather than writing ourselves. The bug has been reported to upstream GCC (about a different library's use of this code): https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106709 For our test case, since this isn't our original code and there isn't actually a bug in it, suppress the incorrect warning rather than trying to modify the code to work around the compiler issue.
