spring 0.74b3 segfaults on startup (feisty)

hi,
I used spring without any error for a week or so on ubuntu feisty, but suddenly it segfaultet while playing a singleplayer skirmish with the Star WarsMod (the fixed Version).
since spring always crashed with a segmantation fault when I tried to fire it up again, I uninstalled spring with my packetmanager, deleted (probably) all spring (configuration-)files and compiled from source.
but spring still had the same error.
traceback from the source-version:

(gdb) q
The program is running. Exit anyway? (y or n) y
Perhaps there´s a conflicted config file I´ve overseen to delete.

Could you set StdoutDebug to 1 in ~/.Springrc and run it again (preferably in debugger) so I can see the datadirs and what exactly it was doing while this happened?

hmmm, I tried it with and without debugger...
I checked the debug option to be enabled, but with debugger it seems to be the same as before
(here is the debug of the current try), and without gdb there´s coming nothing except
Code: Select all
$ /usr/local/games/spring
Segmentation fault (core dumped)
Do you know where to find this "core"?
I think spring crashes before it can create debug information. Or this has something to do with the console verbose level (in "Settings++"). I tried with verbose level on 10.
Thanks for the quick answer btw!

No, the verbose level thing was never implemented.
Well if you set this StdoutDebug option to 1 and it still outputs the same then it's crashing really really early, but I suppose it's possible. (Looking at the stacktrace again it's very well possible actually that it did not yet print anything to log/stdout.)
I'll take a look at the source once I'm at home (if I remember
)

verbose level is used in AI messages though. When the AI send a message to the console it has to provide a priority value which is then compared against the verbosity level.

well, this is probably still the same as the one before. is there any further option in the debugger than "backtrace"/"bt" ?
What I´m thinking about is, that it did work well for a week and then suddenly after the first segv neither the .deb nor the later compiled source work.
Maybe it´s caused by an update or by a corrupted config.
(can spring corrupt configs?)
would it be an option to replace "~/springrc" ?
perhaps someone could give me his springrc so we can check this...

No not a config. But it could be, and I suspect that, that a corrupt .sdz/.7z file is in one of the directories where Spring looks.

what directories are these?
sry for not responding, I unfortunatelly crashed my NVidia driver so I had to fix that issue first...

/mods
/maps
If I recall correctly...
