Description:
------------
When I run the code shown below, PHP generates a segmentation fault. The object $o has a dynamic
property $p. When trying to find out the type of $p, the segmentation fault appears.
Test script:
---------------
class C { }
$o = new C();
$o->p = 0;
$ro = new \ReflectionObject($o);
foreach ($ro->getProperties() as $rp) {
echo $rp->getType()->getName();
}
Expected result:
----------------
segmentation fault (core dumped)
