I'll check, but I'm pretty sure I'm not doing anything like that.

Actuall, it doesn't act differently every time it is run. Sometimes it
works exactly as I expect. Other times, every run has a different
error.

I wonder if it may be caused or related to a threading issue, or some
other program malfunctioning. I'm running it on a dual core machine.
Does the garbage collector run on a different thread? Could that cause
a race condition? This looks like a multithreading problem if it isn't
hardware.
