Discussion:

Subclause 17.13.2 [cstdarg.syn] p1 bullet (1.2) states (among other things):

[…] If the parameter parmN is of a reference type, or of a type that is not compatible with the type that results when passing an argument for which there is no parameter, the behavior is undefined.

Unlike the C standard, the C++ standard has no notion of 'compatible types', thus the meaning of this sentence unclear.
