First call of getservbyname in module causes segm fault

           Summary: First call of getservbyname in module causes segm fault
           Product: Apache httpd-2.0
           Version: 2.0.40
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Core
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: uwe@steinmann.cx


I tried both catacomb (web dav with mysql as an repos) and php4
as an apache module. Both show the same error when getservbyname()
is called.

#0  0x00000000 in ?? ()
#1  0x0ed61690 in _nss_db_getspnam_r () from /lib/libnss_db.so.2
#2  0x0ed61794 in _nss_db_getspnam_r () from /lib/libnss_db.so.2
#3  0x0ed60afc in _nss_db_endservent () from /lib/libnss_db.so.2
#4  0x0ed60eb0 in _nss_db_getservbyname_r () from /lib/libnss_db.so.2
#5  0x0fb4ddb4 in getservbyname_r () from /lib/libc.so.6
#6  0x0fb4dbfc in getservbyname () from /lib/libc.so.6

In catacomb getservbyname() is called within mysql_init() which
itself is called when the module is initialized.

To verify this behaviour I tried php4 with mysql support. This one
shows the same behaviour, though the call to getservbyname() isn't
done be mysql_init() but earlier in php right before calling mysql_init().

I can verify this for apache 2.0.40 and 2.0.36. I used two different
versions of mysql as well (one of them self compiled).

My system is GNU/Debian Linux for PPC (stable and some stuff from testing)
glibc 2.2.5-14
