Description:
------------
I generate php files using my pro file, when I invoke serializeToString method, Segment fault: 11 error occurred.

Test script:
---------------
proto file:
syntax = "proto3";
package com;
message A
{
    string str = 1;
}
message B
{
    A a = 307001;
    string json_body_req = 308000;
}

===================================
php test file:
<?php
$b = new \Com\B();
$a = new \Com\A();
$a->setStr("hello");
$b->setJsonBodyReq("world");
$b->setA($a);
$str = $b->serializeToString();

$b = new \Com\B();
$b->mergeFromString($str);
var_dump($b->getA()->getStr());

Expected result:
----------------
string(5) "hello"

Actual result:
--------------
Segmentation fault: 11

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

We do not maintain the protobuf library.

Look for any existing bug reports that match your problem, and if you can't find one then report it there. If Google says the bug is in PHP then we can reopen this.
