Hahaha, finally figured out what was going on here.
The definition of types_match and single_use violate the C++ ODR in a
non-optimizing compilation (ie, then they do not get inlined). There'll be two
implementations of each function -- with different semantics and the linker
will just pick one willy-nilly.
Easily fixed by making them static inlines.
Doh!
