because dg.ptr would be used to retrieve the offset of the
locals variable used in the parent stack or the address of a
class instance (the this). But this is not required at all
here. The opposite way would lead to various access violation.
That only works because foo doesn't have any parameters. When
you add even just one, things will go wrong.
True if was forgetting that the context is a hidden parameter...
Maybe it depends on the calling convention too ?
