Something seems to have changed, your code proves that. But AFAICS
nothing is said in the docs regarding the stack contents on hook
functions calls, so you seem to be purposely hitting undefined (tm)
behaviour ( I may have misread the docs, please point me to the
appropiate point if you know some place where stack contents are
documented ) .
