core dump while chatting password?

Latest cvs samba on OSF1, encrypted passwords, remote password change with
smpbasswd -r, unix passwd sync = yes:

[1998/12/23 12:55:00, 100] smbd/chgpasswd.c:talktochild(276)
  talktochild: chatbuf=[*] responsebuf=[changing NIS passwd entry for thimm
  sh: 15514 Memory fault - core dumped

The dump came from yppasswd having a segment violation, installed more than 9
month ago and used by 700+ users, and noone complained about core dumps until
now. So I think something is wrong with the chat wrapper. On the other hand
non-NIS passwd programs work with the chatter (?)

Here are the dump infos:

GDB 4.16 (alpha-dec-osf4.0), Copyright 1996 Free Software Foundation, Inc...
(no debugging symbols found)...
Core was generated by `passwd'.
Program terminated with signal 11, Segmentation fault.
Reading symbols from /usr/shlib/ debugging symbols found)...done.
#0  0x3ff8018e108 in __crypt16 ()
(gdb) where
#0  0x3ff8018e108 in __crypt16 ()
#1  0x1200054a0 in checkoldpasswd ()

Any hint? How could I spott the error?

Thanks, Axel.
