I attached the complete output (stdout and stderr incl. debug info). Maybe a trained eye can make something out of it.

(my previous text, not so promising: )

Spoiler:

This is the part just before the segfault (but debug output continues afterwards):

Segmentation fault

update: Now I also attached my gdb output.
some interesting lines:

I hope this is helpful
