Using Delphi 11.3 and hooking TCustomForms.MakeFullyVisible, passing the address of TrampoLine pointer throws 'Invalid TrampoLinePointer' for me:

var
TrampolineMakeFullVisible: Pointer;
//
TrampolineMakeFullVisible := InterceptCreate(@TCustomForm.MakeFullyVisible, @InterceptMakeFullyVisible);
//
InterceptRemove(@TrampolineMakeFullVisible);

Passing just the pointer works without throwing an exception:

InterceptRemove(TrampolineMakeFullVisible);

Am I doing something wrong?
