This is derived from a ~2000 line module, I'm beat:

import std.traits;

struct PointImpl(T) 
{ 
    @property auto test() 
    { 
        return PointImpl!int(); 
    }
}

struct Wrapper(T)
{
    T payload;

    auto test()
    {
        static if (is(ReturnType!(T.test) == void)) { }
        return payload.test;
    }
}

Wrapper!(PointImpl!int) point;

void main()
{
    auto x = point.test;
}


It's hard to explain the point of this code like this, but anyway I get back:
Assertion failure: '0' on line 1117 in file 'glue.c'

If I remove the `static if` statement the assertion goes away. I also had some
Expression assertion errors, but it's too damn tiring to produce a minimal
test-case.
