I'm pretty sure it does work. I think it's an misunderstanding due to the error
message I reported. I found this issue first on Linux 32bit and the reproduced
it on OS X 64bit where the error message is from.

It's my fault for creating the report this way, I thought the platform didn't
matter. This is on Linux 32bit.

Any way. Do you have a suggestion for a workaround? What is the appropriate way
to forward varargs?
