No, in first too.
Ive got an assertion : assert(vt && vt->gcvt); in
vtable_get_gcvt_raw(Partial_Reveal_VTable* vt)
Call Stack:
vtable_get_gcvt_raw(Partial_Reveal_VTable * vt=0x042d8088)
obj_get_gcvt_raw(Partial_Reveal_Object * obj=0x10941da0)
object_is_array(Partial_Reveal_Object * obj=0x10941da0)
vm_object_size(Partial_Reveal_Object * obj=0x10941da0)
