That's not a very useful crashdump. At the very least, do bt full in gdb after that.

Please see this:

Why do you use gdb manually? Don't the automatic crashdumps work for you?

For some reason, it doesn't seem to be detecting the debugging symbols, even though they are installed.

Recompile with debug turned on:
./configure --enable-debug=true

Replying to Warzone2100/old-trac-import#1262 (comment:6):

Recompile with debug turned on:
./configure --enable-debug=true

Oops. make the ./configure --enable-debug=yes

cybersphinx commented

Hm, building your package from source on a Debian unstable system works, it starts normally, and the crashdumps (--crash to test) also work. Probably Ubuntu screwed something up again.

--enable-debug is not needed, as long as you have -g in your CFLAGS (and not even recommended, since it enables asserts). --with-opengl is useless, btw, since the game doesn't work without OpenGL. --with-ogg shouldn't be needed as well.

Should I file a bug on Launchpad? Which package do you think might be causing this problem?

cybersphinx commented

dh_strip, which makes the -dbg package, is in debhelper.

For the Warzone crash, can you just compile the source with ./configure&&make, then run src/warzone2100? That should give a good crashdump.

michael@... commented

I tried building manually, but no crashdump is given. The GDB output was exactly the same. I can tell you, however, that it has something to do with sound, because running with --nosound works correctly. (except for the lack of audio output, of course)

cybersphinx commented

Can you downgrade OpenAL (to 1.4 or something like that)? That might help. Though it is strange that the crashdumps don't work...

michael@... commented

I tried downgrading OpenAL to version 1.9 (the last released version in Lucid) and both my custom compiled version and the packaged one now work. I will file a bug in OpenAL for ubuntu.

cybersphinx commented

Ok, that solves the crash... still leaves the question of the crashdumps. Do you have any CFLAGS set that override the ones in debian/rules?

michael@... commented

I don't think so. All I did was download the source for an older version, update to the source for 2.3 beta4, and then change the version number in the changelog. And the crashdumps didn't work with the ./configure&&make build either.

cybersphinx commented

Hm, the original problem is solved, so I guess we could close this ticket... but I really don't like having binaries where the crashdumps don't work. What does "set|grep FLAGS" say on your system?

michael@... commented

The only output is:

CRLF

cybersphinx commented

What? That doesn't even make sense, how does grep find "FLAGS" in there?

michael@... commented

Carriage return+Line feed

It doesn't output anything.

cybersphinx changed status from new to closed

cybersphinx set resolution to external

cybersphinx commented

Oh. Ok. Well, I tested your binary packages here, and whatever prevents the crashdumps from being created is local to your system, it works here. Though I noticed you use --with-distributor=Debian in debian/rules, you should change that.
