Today I emerged mysql, apache, PHP5, phpmyadmin and joomla on a ~x86 host to be able to play a bit with Joomla. But I can not get phpmyadmin or Joomla to work (both with the same error). Mysql and apache starts OK and the the phpmyadmin setup page (http://localhost/phpmyadmin/setup) loads fine - but when I press the Save-button all I get back is a blank page (the same is true for Joomla - after selecting the language and pressing Next - all I get is a black page)- In apache's error-log I see the following in both cases: [Sat Dec 04 19:54:35 2010] [notice] child pid 3134 exit signal Segmentation fault (11) I've had a look at bugs.gentoo.org but could not find anything with php-5.3.3 or Apache-2.2.16 (just with older versions of php and Apache). That's why I'm opening a new bug. Reproducible: Always Steps to Reproduce: 1. Point browser to http://localhost/phpmyadmin/setup 2. Click Save Actual Results: Blank page appears and "Segmentation fault" error message in the apache error log. Expected Results: The phpmyadmin page should appear and no error in the error log.

This is a wrong-code bug with gcc 4.5.1, see: http://forums.gentoo.org/viewtopic-t-855112.html If you revert to gcc-4.4.5 and rebuild apache it should work.
Yes, after reverting back to gcc-4.4.5 it's working again. Do you know if there is a bug open for this gcc problem here at bugs.gentoo.org? I could not find one... Thanks for you support and keep up the good work.
A new bug has been opened for gcc (http://bugs.gentoo.org/show_bug.cgi?id=347785)

Had a similar issue with mod_ssl segfault'ing all the time and "fixed" it compiling apache with CFLAGS "-O" (not -O2 nor -O3) See: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46488
(In reply to comment #0) Same problem with gcc-4.5.2 and apache-2.2.17
See Mandriva ticket : https://qa.mandriva.com/show_bug.cgi?id=61384 It seems that the problem doesn't occurs with apache 2.2.17 (per comment #28)

should be fixed with apache 2.2.17
