What happens in that in one kind of compilation, @nogc is
deduced for a function. But in another compilation, it isn't.
Thus references to the function will have the wrong mangling,

At the moment you can work around it by explicitly adding the
annotation.
Cannot add something to a compiler internal function (e.g.
__fieldPostblit), @nogc and pure are infectious, the templates
are instantiated with different types where some instantiations
require deducing @nogc/pure/..., others require @gc/impure/...,
annotations cannot be applied conditionally (at least I don't
know how), cannot add @gc, cannot add @impure, etc.
Not that it helps you at the moment, but thus is addressed by my
attributes DIP.
I suppose you could abuse @allocSize to force @gc, but thats very
ugly.
