open-invaders crashes with exit status 139. We confirmed the crash by
re-running it in a fresh debian unstable installation.

The attachment [1] contains a testcase (under ./crash) crashing the
program. It ensures that you can easily reproduce the bug. Additionally,
under ./crash_info/, we include more information about the crash such as
a core dump, the dmesg generated by the crash, and its output.

Dear Debian QA Group,

Thanks for keeping this game going in Debian.

This bug report seemed partly automated and did not fully explain what the
bug was, so I thought I would clarify it. If open-invaders is started
without an X display, e.g. if DISPLAY is unset, then it segfaults instead
of exiting gracefully:

$ unset DISPLAY
$ open-invaders
/usr/share
Segmentation fault
$

This happens because the program does not check the return code of allegro_init().

The attached patch fixes the problem.

Thanks again,
John.
