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.
