Try it with previous compiler version. It looks like a bug I've reported 
not so long ago: in 2.051 functions with 'auto' result type and at least 
one parameter cause segfault during compilation when they are in a 
separate module. I can't remember issue number right now (and have no 
internet connection to find it), but it's pretty recent.
