You can type this

strace /etc/init.d/httpd start

and read all systemcall and library for start afret do work to crash apache and see error on terminal

you can see log file apatche in /var/log

Sorry about my typo

i mean:

2)memory/cpu fault(rarely and normally other applications are not work properly) check cpu fan and run "memtest" for memory check

Normally segmentation faults mean:

1)application fault

2)memory/cpu fault(rarely and normally other applications are not work properly) check cpu fan and ren "memtest" for memory check

also check apache and /var/log/messages files for more information

apache create dump file(see httpd.conf) but reading dump needs more expreience

3)mismatch shared library

try to ./configure & make & make install

read README file and execute ./configure --help

to enable debug mode
