Description:
------------
Hello.
Our system is Solaris 11 with nginx+php-fpm.
Sometimes our programmer execute a few scripts which generate an exeptions which 
doesn't processed by the application and that's why hangup a php-fpm. I try to 
use version 5.4.3 and 5.4.8, but it still hangup. 
When we use version 5.3.9 - exections was generated, but php-fpm didn't hangup.

Also, i try to disable a xdebug, rebuild with gcc/solaris studio but it nothing 
changes.

php build with this parametres:

--with-mysql=/usr/mysql --enable-embedded-mysqli --with-gd --with-jpeg-dir=/usr 
--enable-session --enable-sockets --with-openssl --with-iconv --enable-mbstring 
--enable-exif --with-zlib --enable-fpm --with-curl

build arch is amd64


Actual result:

Thanks for reply, but I have already done it. Also, I've already written about
