Hi,
Dereferencing argv[0] without checking for argc == 0,
is most probably not a security issue, but it could be a sign for
a bit sloppy programming.

I created a test to see which programs segfault when started
with an empty argv
https://github.com/eriksjolund/empty-argv-segfault-check

Please have a look if anyone is interested.
Kind regards,
Erik Sjölund
