Confirmed: that looks like a valid use case to me! ;-)

I hope this is now fixed in Trunk: note however, you can still generate 
types with type_with_alignment<> which can't be passed through a function by 
value - but only if no other "ordinary" type is available - previously 
type_with_alignment<> wouldn't have compiled in these cases anyway.
