The C example that come with my Debian/Ubuntu package gave me segmentation fault error, after successfully compile into binary.

Here are my steps, will file another bug report after I go home tonight:

Generate:

  gengetopt --input=./sample2.ggo --func-name=my_cmdline_parser
--file-name=cmdline2 --unamed-opts --no-handle-help --no-handle-version

Compile:

  gcc -DPACKAGE='"cmdline2"' -DVERSION="1.1" -o main2 main2.c cmdline2.c


Run:

$ main2
main2: '--int-opt' ('-i') option required
main2: '--long-opt' ('-l') option required

$ main2 -i 3 -l 5

$ main2 -h
This is a simple test for gengetopt
Segmentation fault
^^^^^^^^^^^^^^^^^
