I'm having this same issue (at least it sounds the same).
I'm running 12.04 Ubuntu on a 32 bit machine. A few days ago I succumbed to the repeated notifications from the system that "Updates were available" and click "Oh, OK, go ahead and update the darn thing!"
Before I did that I had a working sim version of EMC 2.5. After updating Ubuntu, it no longer works. The toolchanger screen pops up, and the terminal reports a few "waiting for s.axes" before quitting.
Rather than try to get to the bottom of that, I thought I'd go ahead and load new source, build it, and go from there. I followed the directions
here and things seemed to go correctly. But I only get the splash screen (2.6.0~pre), the toolchanger screen, and then a crash.
Here's the terminal output:
bdugan@ben-gateway:scripts$ ./linuxcnc

as well as in the output of the shell command 'dmesg' and in the terminal
And here's what's in linuxcnc_debug.txt:

This is my first post here, so please tell me if I'm posting inappropriately in some way! I've been using EMC (now linuxcnc) for 7 years and it has been a huge help. Normally I can get to the bottom of problems with searchng on these forums or on the wiki. I think my problem this time is trying to use the simulator on a new-ish version of Ubuntu.
Thanks in advance for any pointers!
