Description of problem:
'/etc/rc.d/init.d/httpd start' or '/usr/sbin/httpd' both appear to complete
successfully (in the former case, it lists 'OK', and in the latter, a command
prompt is returned - in both cases syslog shows 'httpd startup succeeded'),
however, the process only lives for a few ticks, and then dies an abrupt death.

I produced a minimal httpd.conf to reproduce this problem:

    User                    apache
    Group                   apache
 
    ServerRoot              "/etc/httpd"
    PidFile                 "/etc/httpd/run/httpd.pid"
 
    Listen                  8000
 
    LoadModule perl_module modules/mod_perl.so
    LoadModule php4_module modules/libphp4.so
    LoadModule ssl_module modules/mod_ssl.so

If any of the LoadModule lines are commented out, the problem
disappears. All three seem to need to be present in order for me
to reproduce my difficulty. The strace output for a sample failure
can be found at:

     http://mark.mielke.cc/httpd.strace.txt

From the strace output, it looks like /usr/lib/php4/snmp.so is
doing something improper. There is another ticket that describes
similar behaviour to mine in bugzilla that refers to issues with
php4/snmp.so but is not specific enough, and describes different
behavior.

Version-Release number of selected component (if applicable):
httpd-2.0.45-14

How reproducible:
Always

Steps to Reproduce:
Execute /usr/sbin/httpd using the config file from the
Description text.

Actual Results:
httpd dies with sigsegv shortly after it successfully starts.

Expected Results:
httpd should live.
