Changes in timidity code were not quite successful, it seems. Upon starting a new game (or waiting long enough for demos to start), vavoom segfaults. (it probably happens with savegames too, but being on svn for so long, I don't really have any reliable save) Best result I could get is following gdb backtrace:

#0  0x0831dae6 in LibTimidity::read_config_file(char const*) ()
#1  0x0831d6cc in LibTimidity::read_config_file(char const*) ()
#2  0x0831d6cc in LibTimidity::read_config_file(char const*) ()
#3  0x0831e30c in LibTimidity::Timidity_Init() ()
#4  0x08232a8e in VTimidityAudioCodec::Create(VStream*) ()
#5  0x0822a48c in VAudio::PlaySong(char const*, bool) ()
#6  0x0822aa42 in VAudio::CmdMusic(TArray<VStr> const&) ()
#7  0x0822d40d in TCmdMusic::Run() ()
#8  0x080cc9c5 in VCommand::ExecuteString(VStr const&, VCommand::ECmdSource, VBasePlayer*) ()
#9  0x080cda7c in VCmdBuf::Exec() ()
#10 0x081093d5 in Host_Frame() ()
#11 0x082e739c in main ()

Near the end of debug file (after several "Log: FIXME: Implement "map" in TiMidity config."), I'm getting this:

Dev: Spawning server map01

I don't quite remember what my previous checkout was, but it seems it happened quite recently.

I've had the same error before, we are trying to track down the problem... unfortunately... it's not simple to fix <!-- s:( --><img src="{SMILIES_PATH}/icon_sad.gif" alt=":(" title="Sad" /><!-- s:( -->.

So, after doing a bit more tracking: my timidity setup uses eawpatches segfault happens while parsing this config file:

dir /usr/share/timidity/eawpatches
source gravis.cfg
source gsdrums.cfg
source gssfx.cfg
source xgmap2.cfg

However, it doesn't happen, if I comment out three last lines. The problem seems to lie in those files (as the order doesn't matter), however it worked fine before the changes and there are no my changes in those files. I'm starting to suspect r4178 is at fault, on the other hand though, I think it worked even after that.

The problem seems to be related to the way Timidity is loading and assigning patches from config files to the instruments, I've got an idea to try to fix this, but I'm unable to work on it for now...

Fixed.
