Description szaka 2003-07-30 23:06:49 UTC 
Description of problem:
Statically linked Apache children immdiately crash (sig11) in glibc's initgroups
when using OpenLDAP.

Version-Release number of selected component (if applicable):
latest glibc and openldap shipped by Red Hat 9. The glibc errata didn't fix the
problem.

How reproducible:
Always

Steps to Reproduce:
1. install openldap
2. make sure the 'group' line in /etc/nsswitch.conf is 'file ldap'
3. echo "main(){initgroups("root",0);} > a.c ; gcc --static a.c
4. ./a.out
segmentation fault


Actual Results:  segmentation fault

Expected Results:  no segmentation fault
Comment 1 Jakub Jelinek 2003-07-31 15:52:00 UTC 
Works for me in glibc-2.3.2-56.
Also, it gives a new link time warning:
Using 'initgroups' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
as using NSS/iconv in statically linked programs is really bad idea.
