I just had a look at the sources and probably found an unrelated
glitch:
compare.c:verify_volume()
518 void
519 verify_volume (void)
520 {
[...]
579 while (1)
580 {
581 enum read_header status = read_header (false);
[...]
600 if (status == HEADER_ZERO_BLOCK || status == HEADER_END_OF_FILE)
601 break;
605 }
606
607 access_mode = ACCESS_WRITE;
608 now_verifying = 0;
609 }
I didn't verify, but shouldn't this read like this?
