static link csh/tcsh dumps core

[Chuck Cranor <chuck%ece.cmu.edu@localhost>]

I've been updating one of our alphas here at CMU with 6.0.1
(was running 5.1_STABLE from Feb 2011 before).

The upgrade went fine, but when I started updating pkgsrc
I noticed that my /bin/tcsh (from standalone-tcsh package)
dumps the core.

I dug into it a bit more and discovered that even csh dumps
core if it is static linked:

% uname -a
NetBSD omega.pdl.cmu.local 6.0.1 NetBSD 6.0.1 (GENERIC-$Revision: 1.343 $) #1: 
Tue Feb  5 13:43:34 EST 2013  
chuck%omega.pdl.cmu@localhost.local:/home/netbsd/6/src/sys/arch/alpha/compile/OMEGA
 alpha
% /bin/sh
$ exit
% /bin/csh -f
% exit
% exit
% 
% /rescue/sh
$ exit
% /rescue/csh
Segmentation fault
% 


Now if I run /rescue/csh from my old 5.1_STABLE system it works:

% 
% /home/netbsd/5/alpha/destdir/rescue/csh -f
% exit
% exit
% 

so the problem was introduced sometime in the last 12 months.

is anyone else seeing this with /rescue/csh on their alpha?
what would cause something like this?
