Although my program does use threads, I don't think it had gotten there
by the time the problem occurs. Doesn't gdb print a message when a new
thread appears? Therefore, I ignored the bugs I saw that mentioned threads.

Here is my attempt at a backtrace. I hit CTRL/C when it got to the 
complaint about internal-error.
