Hi Folks,

I've written a Prolog program which runs correctly on Solaris and also on
Windows NT for small data sets, but on Windows NT with a large amount of data
it appears to hang.  It's generally doing stuff related to writing text to a
stream but I'm not sure as I can't see how to break in to see what it's up to.
 So, questions:

  - Are there any known problems or predicates I should be avoiding (I'm not
    using signals, btw)?

  - How do I break in and see the current goals, as in ctrl/c under Solaris?
    ctrl/c in plwin does nothing, whilst plcon says "FATAL ERROR...received
    signal 2 (int) while in 20-th garbage collection".

  - Is there some other way I can get some visibility on what's happening?

I don't really want to submit a bug report based on so little information...

Thanks for any help.
