Applies on all platforms. Segfaulting in template.c 854

Reduced test case shows it's caused by a tuple this() struct constructor.

struct Foo {
    this(U...)(U values)  { }
}

void main(){
  new Foo;
}

Segfaulting in template.c (854)
    nfargs = fargs->dim;        // number of function arguments

PATCH: template.c(854)
    if (!fargs) nfargs=0;
    else nfargs = fargs->dim;        // number of function arguments
