Re: Problem releasing ORB.

[Craig Wright <spiral cs unm edu>]

I've attached some files with various output you've requested. I don't 
know if the original message contained this, but I'm running Redhat 7.2 
with gcc 2.96. It's linux 2.4.7-10smp if that helps any... this is the 
default kernel.

checkOutput.txt is the output of 'make check'

I can't get it to fail again.... ugggg. I wasn't imagining this though. 
;) If/when it happens again I'll let you know.

It dies on an assertion as you will see in the attached file.

Here's a stack trace.

This comes from running ./server in test/everything and ./client in 
test/everything. This is te stack trace of the client. The server is fine.


$ ping `hostname`

I stuck a call to gdb before the " exec $program ${1+"$@"}" line in the 
shell script. This is the output of the program with the stack trace.
