As far as I can tell, this isn't generally true. For example, dmd may 
get fixes/changes in name mangling, making it incompatible with old 
object files. Since you've already cleaned everything, this doesn't seem 
to be the issue here. But don't assume that a newer dmd is guaranteed to 
work with older object files. It isn't.
