[Bug] maxicode copies to many chars #27

Closed chaosben closed 2 years ago

chaosben commented 11 years ago

The loop at line 414 in maxicode.c counts up to 9 and copies 10 chars into "substring" but there are only 9 chars to copy, because only 9 digits are to be compressed. So the loop should only count up to 8. That isn't a bug which causes an error, because "atoi" is tolerant with non-digit-chars after the number. But it is wrong and could cause problems in future.

This issue no longer exists in the current version of Zint, thanks for the feedback, closing now.
