I cannot reproduce your problem. A test script run under mod_php gives
the expected result (same as the command line output).

Could you post the list of your enabled modules ? (ls -l
/etc/apache2/mods-enabled)
Could you attach your apache configuration ?

The only file in /etc/apache2/conf.d/ is "charset"

Could you try to disable your Trac configuration ?

[Finjon Kiang (kiange)]

I tried to remove lines below "Include /etc/apache2/sites-enabled/" in apache2.conf and restart apache. There's the same error.

I also tried to execute the test script both in user directory (/home/kiang/public_html) and root directory (/var/www). Both generated the same error message:

[Thu Jan 31 14:20:13 2008] [notice] child pid 10758 exit signal Segmentation fault (11)
[Thu Jan 31 14:25:19 2008] [notice] child pid 10761 exit signal Segmentation fault (11)

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.
