Hi,

d1x-rebirth crashes when I try to start a new game or load a saved game. Here's
one way to reproduce it:

1. Select a pilot
2. New game
3. Select level and difficulty

The crash occurs just after selecting the difficulty.

d1x-rebirth -debug -verbose gives the following output (fish shell in Swedish):

...
(quite a lot of initiaization output is omitted. Please let me know if you need
it)

fish: 'd1x-rebirth -hogdir Spel/Descen…' terminated by signal SIGSEGV
(Minnesadress korsar segmentgräns)

I use a hogfile that I downloaded from the DOS game archive on archive.org,
https://archive.org/details/msdos_Descent_-_Levels_of_the_World_1995.

I haven't run d1x-rebirth for some months, so unfortunately I can't tell when
this problem really started (I guess the bug is not actually in d1x-rebirth but
in some dependency).

Hello Mikael,
maybe you could install systemd-coredump and look into output
of "journalctl -e" after such a crash happened again.

For more information please have a look at [1] about several
ways to collect some more information that might help the
maintainers.

Kind regards,
Bernhard

Hi all,

I believe I've ran into the same error as the original submitter. I find that
the error appears when trying to view the credits as well. Here's a backtrace:

I find that if I disable sound in the options, the program no longer crashes
and I can play the game without any other problems.
