I'm not sure what it is that the OS is complaining about.
it looks like it is trying to mmap() stdin...
attached you find the complete trace.

Ah, I think I see the problem. FreeBSD requires the fd argument to be -1 for MAP_ANON, but Linux doesn't care which is why it didn't fail in this way for me. I'll commit a patch as soon as it validates.
Patch pushed... I'd be grateful if you could test it - thanks! Simon
