By the way, Richard, I just want to note that while this is obviously a
compiler bug, it is only being triggered for the original test case because of
the uninitialized variable i in sha1_update:
void sha1_update(SHA1_CONTEXT* context, unsigned char* data, Q_UINT32
len) {
Q_UINT32 i, j;
if((j + len) > 63) {
for ( ;
i + 63 < len;
i += 64) { transform(context->state, &data[i]); }
}
}
I don't know if that was a consequence of your test case reduction or not.
