I ran into a related issue recently.  A moderately popular open source
project uses nonportable constructs involving varargs function calls,
passing NULL, uncast, as a varargs argument and expecting it to be a
nil pointer when fetched in the called function.  Between a lack of
implementations to point to where it'll fail and some very creative
reading of the standard on the part of the "other side", I was unable
to convince them this was invalid code....
