And I can't use the httpd -X method since apache crashes on startup. Any clue ? If it's necessary I can have PHP recompiled as a debug build... ok, i'll do that. ------------------------------------------------------------------------ [2003-05-16 04:36:47] derick@php.net Please unload Xdebug too if you report bugs ------------------------------------------------------------------------ [2003-05-16 04:17:13] magnus@php.net Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2003-05-16 04:11:48] katana at katana-inc dot com Apache crashes on startup. I just add the correct path to browscap.ini in php.ini, run configtest and i get a segmentation fault. I get the same error when starting httpd manually. Unfortunatelly i don't have time enough at the moment to recompile php as debug build... Here is my config line: './configure' '--prefix=/usr/local' '--with-apache=/root/Apachetoolbox-1.5.64/apache_1.3.27' '--enable-exif' '--enable-track-vars' '--with-calendar=shared' '--enable-magic-quotes' '--enable-trans-sid' '--enable-wddx' '--enable-ftp' '--enable-inline-optimization' '--enable-memory-limit' '--with-zlib' '--with-jpeg-dir=/usr' '--with-png-dir=/usr' '--with-zlib-dir=/usr' '--with-iconv' '--with-mhash=/usr/local' '--with-mcrypt=/usr/local' '--with-openssl=/usr/local/ssl' '--with-curl=/usr/local' '--enable-bcmath' '--with-gettext=/usr' '--with-mysql=/usr/local' '--with-mnogosearch=/usr/local/mnogosearch' I also have XDebug 1.2.0 loaded. browscap.ini: Last updated 2003 May 13, Tuesday 11:42:27 PM GMT. Oh, and it was working correctly with the same browscap.ini with 4.3.2-RC2 and the same setup. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23657&edit=1
