This is not an Apache problem. The problem is in your Siteminder configuration.
Configuration of the WebAgent configuration for libmod_sm20.so is tricky, especially if you are using one of the early versions of this module, specifically in 5QMR6. In 5QMR6 the agent is very unstable. If you are using 5QMR6 your should consider migrating to 5QMR7 HF003. Keep in mind that the configuration of mod2_sm.so is very different from the configuration of libmod_sm20.so.
Without having seen your conf, I guess the problem is in your configuration. Read the WebAgent Installation Guide as well as the release notes and follow the instructions carefully. Make sure your environment variables NETE_WA_PATH, NETE_WA_ROOT, LD_LIBRARY_PATH or Linux equivalent are set according to the documentation. Create the WebAgent.conf file using the script <SM_ROOT>/siteminder5/webagent/bin/nete-wa-config

Is it segfaulting? Try:
# gdb /usr/sbin/httpd
...
(gdb) run -X
then enter "backtrace" if it segfaults.
