Hi,

thanks to all that helped.

I've just found the problem. When the program is started with gdb the 
commandline differs. This means that argv[0] is different and that has the 
effect that our commandline parser needs a different number of allocations.

Starting the programm with:

gdb ./prog

results in an argv[0] of

/home/ponto/source/prog 

Starting it with

./prog

results in an argv[0] of

./prog
