I don't think it's a bug. It seems that when the old ABI is specified - ELF toolchains emit both old and new manglings (using non-weak aliases). Darwin can't do that (at least, for now) so it only emits the mangling appropriate to the ABI rev. SO - we should test that all platforms emit the expected mangling for two representative ABI versions. I suppose that the ELF toolchains could also do a third test for the "bonus" additional mangling emitted. [[ that is unless it's a bug NOT to emit both - in which case Darwin has more of a challenge ]]
