FreeBSD_3.2 RELASE, USA_RESIDENT_NO, no des/crypto/kerberos.
make world, ports/bash2, make install

I would suggest these, I found a similar problem in the bash.
The corefile generated by bash2 can't be read without aborting gdb.

If you ike to run any tests let me know.
I have the corefiles (bash.core and gdb.core) here.
And no i can't call gdb.core with gdb either.
A small test-programm with SIG11 fatal get debugged,
I have to check when my pids are high again.

kind regards Dirk

It has the internal identification `ports/12174'.

>How-To-Repeat: 

	the new pid of the system has reached a value > 32736.
	The shell itsel could still have an old pid in range.
	using <TAB> key to complete a path on the command line,
	pressing <TAB> twice to get a list that would create a
	question "Display all xxx possibilities? (y or n)"

>Fix: 
	
	this patch seem to fix the problem
