Looks like gcc is too aggressive when optimizing. This fixes the problem for me: --- a/src/lib/sha1.c 2018-01-27 21:35:54.988941316 +0100 +++ b/src/lib/sha1.c 2018-01-27 21:43:17.218926478 +0100 @@ -205,7 +205,7 @@ void sha1_loop(struct sha1_ctxt *ctxt, const void *input, size_t len) { - const unsigned char *input_c = input; + uintptr_t input_c = (uintptr_t)input; size_t gaplen; size_t gapstart; size_t off; @@ -218,7 +218,7 @@ gaplen = 64 - gapstart; copysiz = (gaplen < len - off) ? gaplen : len - off; - memmove(&ctxt->m.b8[gapstart], &input_c[off], copysiz); + memmove(&ctxt->m.b8[gapstart], (void*)(input_c + off), copysiz); COUNT += copysiz; COUNT %= 64; ctxt->c.b64[0] += copysiz * 8;
Only helps against the error in the "sha1" testcase, now the "hash method md5 (test vectors)" test fails in the same method.
Same with 2.2.34

Still an issue? We can send it upstream if so, they're quite good at listening it seems.
Seems to work now. The other errors I see are in bug 727244.
No idea how it worked, but I still see it in 2.3.13-r100.
