Description:
------------
Affects all versions which bundle PHP-FPM. (>=5.3.3)

In fpm_shm_alloc there is a call to memset() to initialise the segment. The 
parameters to memset() are transposed. Since we are [trying to] initialise with 0,  
but passing 0 to size_t, it silently fails to do anything.

Patch attached, tested on 5.3.10 and 5.4.0.
