You're running Fedora, which has 4.1.25, right? I also see that you have a P4
1.8GHz machine... does it happen to have hyper-threading (does it show up as
a dual-cpu machine)? If so, I can tell you now that I've been keeping an eye
on the correlation of problems to 4.1.25, and it's pretty high when it comes
to multi-processor machines. While a single P4 w/HT may not be a true
multi-processor machine, it's close enough. I'd definitely give 4.2.x a go.

Anyway you can see where it's hanging in the server process when this happens?
Actually, if you can tell me what you were doing, I'll try on my machine to
see if I can make it happen, and then we can do some bug hunting together.
Were you simply importing the gcc code?
