You advised me to compile with -Wall first and got no error at all,
when compiling with -Wall -O and -O2 I got some errors but the
programm worked fine. Finally with -O3 it crashed again, but -Wall
said something with initialation, so I did it and now it works.
Thanks for your help out there, You're a really good team (you might
already know, of course).
