If you install dev-php/xdebug and add the extension line to /etc/php/cli-php4/php.ini, the command 'pear' (used for installing PEAR packages) segfaults. Workaround: Remove 'zend_extension=/usr/lib/php/extensions/no-debug-non-zts-20020429/xdebug.so' from cli-php4/php.ini Reproducible: Always Steps to Reproduce: 1. Make a clean install of PHP 2. emerge dev-php/xdebug 3. etc-update 4. emerge some dev-php/PEAR-* packages (Sometimes the first package will work...) Actual Results: root@wintermute dev-php # pear Segmentation fault Expected Results: root@wintermute dev-php # pear Usage: pearcmd.php [options] command [command-options] <parameters> Type "pearcmd.php help options" to list all options. Type "pearcmd.php help <command>" to get the help for the specified command.

I can't reproduce this at all. compile dev-php/php and xdebug with CFLAGS="-O0 -g", do ulimit -c 800000, and come back with the gdb backtrace. 'gdb `which php` core', 'bt'. (and ensure no password strings are in the gdb output when you paste it in).

It's an xdebug bug (see http://pear.php.net/bugs/bug.php?id=194 and http://pear.php.net/bugs/bug.php?id=182). Hopefully will be fixed in 1.3.0 which whould be released RSN.
