PHP version: 5.0.4
PHP Bug Type: Reproducible crash
Bug description: ReflectionMethod::getStaticVariables() causes apache2.0.54
seg fault
Description:
------------
Discovered if I am using ReflectionMethod::getStaticVariables() on a
method that has a static variable that is set to boolean true or false
then php crashes (Apache 2 exists with following error)
[notice] child pid 28346 exit signal Segmentation fault (11)
I tried with php version 5.0.3 initially but upgraded to 5.0.4 and problem
still exists.
Reproduce code:
---------------
class demo_class {
static function myDemo($toggle) {
static $enabled = true;
// do whatever
}
}
$class = new ReflectionClass('demo_class');
foreach ($class->getMethods() as $method) {
$arr_static_vars[] = $method->getStaticVariables();
}
echo "done";
// (normally would output $arr_static_var but just put above
// line for simplicity in this example)
Expected result:
----------------
See a screen with just the word 'done' on it
Actual result:
--------------
Page loading stops immediately (and keeps last page shown displayed.
Apache logs show:
[notice] child pid 28346 exit signal Segmentation fault (11)
(pid of course varies)
If I change the third line in my sample code to:
static $enabled = 1;
(or string) the page does not crash and things display properly
I haven't tested this to see if it also crashes showing static variables
for the entire class (as opposed to the one in the method) but if they
inherit the same code I guess it would also crash but again I haven't
confirmed that.
