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.
