Bug description:Calling function from rebound Closure causes crash
Description:
------------
Calling a function in a rebound closure causes a crash.
This seems to be caused by dmitry's optimizations because this fixes the
issue:
#define CACHED_PTR(num) 0.
Test script:
---------------
class foo {
static function getClosure() {
return static function () {
//causes a crash (fbc not properly defined) in call
after rebinding
echo get_called_class(), "\n";
};
}
}
class subFoo { }
$c = foo::getClosure();
$c(); //foo
$c = $c->bindTo(new subFoo());
$c(); //crash
Expected result:
----------------
No crash.
Actual result:
--------------
