Subject: | Re: [PATCH] gozilla: More robust input error handling |

From: Punit Agrawal <address@hidden>
The check for argc only tests if it is zero rather than any value less
than equal 0. This leads to segmentation fault when fed with invalid
input (Debian bug #715980).
Fix this by erroring out if argc <= 0.

Hi,
The debian bug report includes a reproducer. The patch below fixes the
issue for me and should be considered for upstream inclusion.
Thanks,
Punit
