Summary

0006763: Hang during worldgen, apparently busywaiting for a semaphore?

Description

Worldgen (long history, otherwise default) appeared to hang sometime between 690 and 700. Attaching to it in gdb gave me the following backtrace:

#0 0xf70140b0 in sem_wait@@GLIBC_2.1 ()
   from /lib/i386-linux-gnu/libpthread.so.0
0000001 0xf771c078 in SDL_SemWait () from /usr/lib/i386-linux-gnu/libSDL-1.2.so.0

0000008 0x0804c9f1 in ?? ()

Gamelog.txt was:
*** STARTING NEW GAME ***
Generating world using parameter set CREATE WORLD NOW = 4533333

I haven't yet tried to reproduce it. I've also got the saves/current/ directory if you want me to upload them somewhere.

Additional Information

I don't know if this is actually relevant, but I'm using multiple instances of xorg on my computer; the lockup happened while the X server df was running on was backgrounded. Switching back to the X server df was running on had worked before (normally it redrew once worldgen updated the frame). OpenAL loading failed.
