Hey there,

I'm working on Pegasus (www.openpegasus.org) and we have encountered a
problem on RedHat 9 machine while trying to debug the Pegasus code. Not
sure if its a Pegasus, libc, or RedHat problem - but I figured asking
you guys for some input would help me find the culprit.

The problem is documented at:
http://cvs.opengroup.org/bugzilla/show_bug.cgi?id=404

It basically says:


Under RedHat 9 (which has libc2.3.2) Pegasus (compiled with
PEGASUS_DEBUG=on)
coredumps when debugging under gdb 5.3 (and also the latest snaphost of
GDB from gdb CVS). The coredump reports the backtrace to be:

Any ideas? Thanks!
