The attached pre-processed file compiles fine on i686/x86_64 linux, but not on
darwin. Compiler sources are the same for both, 20091206 ish.
In addition, this passes on Darwin with -O1, but not with -O2.
Darwin error:

This error doesn't make sense. There's a copy ctor that's visible. Clearly
there is something amiss!
