What puzzled me is the following line in /var/log/messages:

any clue on it meaning?
Your program crashed.
The kernel logs unhandled user signals. The x86-64 architecture causes general protection
fault for "non canonical pointers" (pointers where the bits 58 to 63 are not all
0 or all 1).
These are the same as a normal segfault essentially, but mapped to a different exception.
So in short it's just an ordinary bad pointer in your program.
