I thought about that, so I subscribed yesterday :)

I tried it on several little C++ programs I have laying around, simplistic
homework assignments, but first versions that have errors. Some of them it
would crash on and some it wouldn't. There didn't seem to be a common
reason either.

I did so, but crashing it won't give me a core file. Ulimit's set ok and
everything. (I usually have ulimit -c 0) It does do the same recursive
thing though.. I commented out line 93 of we_unix.c, which is the one
above. It still gives me:

Error-Exit!   Code: 11!
Try to save Messages.ESV!
Try to save grades.cc.ESV!
File grades.cc.ESV saved!

etc. etc.

So what do I do now? Any ideas? I hate to have it crashing on me like
this. I went and researched other IDE's for Linux and I always turn back
to xwpe. The only other one I liked (this is console btw, not for X) is
rhide, but it doesn't let you switch between VC's. Bleh.
