a more simple reproduce scripts is:
<?php
class saboteurTestController {
public function isConsistent() { throw new \Exception(); }
}
function testException() {
$controllers = array(new saboteurTestController());
foreach ($controllers as $controller) {
try {
if ($controller->isConsistent()) {
return $controller;
}
} catch (\Exception $e) {}
}
}
testException();

Description:
------------
Test script below runs fine on PHP 5.5.9 and produces segfault on PHP 7 compiled from latest git
with following config:
'./configure' '--prefix=/home/dev/php7/usr' '--with-apxs2'
'--with-xsl=/usr/lib/x86_64-linux-gnu/' '--with-curl'
'--enable-memcached' '--disable-memcached-sasl' '--with-tidy'
'--with-mcrypt' '--with-gd' '--enable-intl' '--enable-zip'
'--enable-soap' '--with-mysql-sock=/var/lib/mysql/mysql.sock'
'--enable-sockets' '--with-mysqli' '--with-openssl'
'--enable-opcache' '--with-zlib'
PHPUnit version 4.7.6
To reproduce segfault its necessary to run both tests from test class:
phpunit saboteurTest.php
If any of tests is skipped like:
phpunit --filter testException saboteurTest.php
phpunit will finish test execution successfully.
Test script:
---------------
class saboteurTest extends TestCase {
function testException() {
$controllers = array(new saboteurTestController());
foreach ($controllers as $controller) {
try {
if ($controller->isConsistent()) return $controller;
} catch (\Exception $e) {}
}
}
function testAny() {
$this->assertTrue(true);
}
}
class saboteurTestController {
public function isConsistent() { throw new \Exception(); }
}
Expected result:
----------------
PHPUnit 4.7.6 by Sebastian Bergmann and contributors.
..
Time: 220 ms, Memory: 8.00Mb
OK (2 tests, 1 assertion)
Actual result:
--------------
PHPUnit 4.7.6 by Sebastian Bergmann and contributors.
