-xc and stack overflow

[Dean Herington]

I'm suffering stack overflow in a program that uses both multiple
processes and multiple threads.  Can anyone help me interpret the
following -xc output?  In particular, which "<...>" reports relate to
the stack overflow?  (I've added a newline following each '>' to
increase readability.)  I think most (if not all) of the reports
preceding the "stack overflow" line reflect EOF exceptions that are
expected.

Also, how can I tell which thread in which process is suffering the
stack overflow?

I'm using GHC 5.03.20020410 on Linux Red Hat 2.4.2-2smp.

Thanks.
Dean
