(>=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. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61430&edit=1
