[2006-02-09 20:53 UTC] jam at zoidtechnologies dot com

Description:
------------
when I run 'pear config-show' as a non-root user, I get a segfault. if I run 'pear config-show' as the root user, I get a segfault. I had previously opened a ticket on this, #6029. this time, I've added some additional information.

[~] [3:47pm] [jam@toast] % pear -V
PEAR Version: 1.4.6
PHP Version: 5.0.4
Zend Engine Version: 2.0.4-dev
Running on: Linux toast.zoidtechnologies.com 2.6.14-1.1644_FC4 #1 Sun Nov 27 03:25:11 EST 2005 i686

Expected result:
----------------
config-show should show the pear configuration.

Actual result:
--------------
