Tab-completion is crashing Bash.

Tab completion is Bash seems to be completely broken. Sometime it works, sometimes it just closes the Terminal window without any errors or anything and, sometimes, it actually gives this crash:

This is with GCC2, BTW.

I just got an different behavior. This time Terminal hang and bash started using almost 100% of one of my cores. I had to kill bash with process controller.
