In case of using the compiled PHP from source, there was no problem.
(PHP5.3.3, snapshot)
In case of using the PHP from rpm binary, there is this problem.
  - Error: Segmentation fault (core dumped) 
  - /var/log/messages: kernel: php[31640]: segfault at 0000000000000004 rip 
000000000042245c rsp 00007fffd2057380 error 4
  - yum install repository: http://wing-net.ddo.jp/wing/extras/el5/SRPMS/

I checked the compile options using phpinfo method, I presume that the casus is 
"--with-system-tzdata".

There is not this option in PHP source.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

This is an unofficial RedHat patch that we've opposed (many times) before. Please take this up with the RedHat folks. Not our bug -> bogus.

I understood about this issue by various information.
I'd like to close this issue because it's due to the customized PHP, including 
unofficial patch.
Thank you for the supporters' kindness.
