Oy, I've been going around and around trying to hunt down some bugs on Songbird. GDB hasn't been very helpful and I'm tyring to get electric fence compiled into xulrunner and songbird. Hopefully that will show some good data so I can track down where the bugs are coming from. If anyone knows of some good tools for debugging threads and/or memory issues (mudflap doesn't work with DSOs ) please send me an email (redfive {at} jgaunt dotcom.
