Hi!

Here's how I can get the game to crash every single time:

  1. Play
  2. BBS Levels
  3. View: WIP / Experimental
  4. Page 2 of 36
  5. 5960 Return to Castle Voxatron
  6. SIGSEGV a few seconds after level start, no action required
 
Version: 0.2.1
md5sum vox: 8b36d1948b1a8174c9c8f29bd1446364
Platform: Linux 3.4.7 amd64

If it's any use, I upped a core file (about 7 MB download). Some basic info:

Happy hunting! (or bleh-old-news-already-fixed-ing, and yes, that's a word)

There is a way to crash the game at the exact same code location, but with a different callstack.

  1. Start BBS Level "4491 Zelda!" (love that search function btw)
  2. Kill the two monsters in the 4th room
  3. Hop into the appearing circle of pillars
  4. SIGSEGV
 
Program terminated with signal 11, Segmentation fault.

I hope my nagging bug reports don't come across as hostile, I'm really impressed with the game. Can't wait to see what the community will build with it! :)

Fixed for the next update.

It probably happens in a few other BBS levels, but I haven't come across any more yet. It was caused by faulty backwards-compatibility when loading pre-0.2.0 levels that contain internal items (player/monster) copied into the main library of props.
