Subject: Re: Re was: [PHP-DEV] 5.0.5RC1 rolled
From: iamstever@gmail.com (steve)

Can valgrind attach to a process like gdb? I somehow doubt it... In
that case, I must admit, I've never used valgrind before. How can I
set up valgrind to check a fast-cgi process?

I tried changing the php5.fcgi file to php505.fcgi and created this as
php5.fcgi:

#/bin/bash
/usr/bin/valgrind --tool=3Dmemcheck --trace-children=3Dyes
--log-file=3D/usr/local/apache2/logs/valgrind
/usr/local/apache2/fastcgi-bin/php505.fcgi

but that didn't work...
