problem: ac_shell and ldap user

We have a problem running the Cadence pks_shell synthesizer under Redhat
8.0: It will produce a segmentation fault and prompt:

    "==> ERROR:   An unrecoverable exception has occurred (SEGV)."

This is not a generell problem because other Cadence software products (e.g.
ncsim) run without any problem.

We use the following versions:
    pks_shell:    @(#)CDS: pks_shell v05.10-s071+2 (32bit) 06/03/03 02:28
(Linux 2.4)
    RedHat:    Linux version 2.4.18-14
([EMAIL PROTECTED]) (gcc version 3.2 20020903 (Red Hat
Linux 8.0 3.2-7)) #1 Wed Sep 4 13:35:50 EDT 2002

The problem seems to be related to LDAP users: running pks_shell as root
works fine because the root user is defined in local files (/etc/passwd,
/etc/shadow). All other users are LDAP users who face the problem described
above. The assumption that LDAP causes the problem stems from tracing the
execution of pks_shell by the "strace" tool which monitors system calls.

We have also verified that all relevant files for user authentication and
DNS are readable by normal users to eliminate a trivial cause for the
problems described:    /etc/nsswitch.conf,    /etc/resolv.conf,
/etc/ldap.conf,    /etc/passwd. The shared objects in use (.so files) have
read and execution rights for normal users too.

So we assume that the segmentation fault might be caused by a programming
error. Has somebody else faced this problem? Or even has got a solution for
it?

Kind regards and Thanks in advance,
Johannes Wolkerstorfer
