New Comment:
I've tested this patch with the current PHP-5.3. The problem still persists.
A quick look with strace makes it seem that a child process is exiting with the
status that is expected from the patch (78) but its parent is not.

For simplicity here I'm going to focus on 5.3 instead of 5.4.
I've tried with the following:
* compiled from source (php.net tarballs) on Ubuntu 12.04
* compiled from source (php.net tarballs) on Debian 6
* Ubuntu 12.04's current php5-fpm package
* CentOS 6 with current php53u-fpm package from IUS
Here's the -tt info:

As a sanity check, I've repeated the problem again on all of the above versions
with the same config. They all show the same error but exit with 0.

Thank you for your interest in PHP.
I can't reproduce the problem.
On my side with both up2date sources for 5.3 and 5.4:
root@dev:/home/fat/dev/php-git/php-5.4# ./sapi/fpm/php-fpm ; echo $?
[23-May-2012 09:32:03] ERROR: [pool direct] cannot get uid for user 'fatprout'
[23-May-2012 09:32:03] ERROR: FPM initialization failed
255
root@dev:/home/fat/dev/php-git/php-5.4# ./sapi/fpm/php-fpm ; echo $?
[23-May-2012 09:32:29] ERROR: [pool direct] cannot get gid for group 'fatprout'
[23-May-2012 09:32:29] ERROR: FPM initialization failed
255
which version of PHP are you using ? (sources from php.net you have compiled or
a package from a distro ?)
Can you send me the result of
php-fpm --version
php-fpm -tt
thx
