Description XC Support 2004-09-21 19:11:58 UTC
Description of problem:

When you set "group: files ldap" in "/etc/nsswitch.conf" and you have 
a statically build application, a call to "initgroups()" call cause a 
segmentation fault.

Version-Release number of selected component (if applicable):

glibc-2.3.2-95.20

How reproducible:


Steps to Reproduce:
1. Set "group: files ldap" in "/etc/nsswitch.conf"
2. Use the following reproducer program. The user is "mysql", but you 
can choose another.

#include <stdio.h>
#include <grp.h>
#include <pwd.h>
#include <errno.h>

main()
{
       struct passwd *pw_ptr;

       char *user = "mysql";

       pw_ptr = getpwnam(user);

       printf("pw_ptr->pw_gid = %d\n", pw_ptr->pw_gid);

       initgroups((char*) user, pw_ptr->pw_gid);
}

3. Compile with "cc filename.c -static"
  
4. Run "a.out".

Actual results:

# ./a.out
pw_ptr->pw_gid = 101
Segmentation fault

Expected results:

# ./a.out
pw_ptr->pw_gid = 101


Additional info:

This only happens when compiling with "-static".
