          Summary: Segfault when trying to use any property of an AA,
                   which is the return type of a CTFE function with inout
                   parameters.

Test case 1 (expected compilable):
--------------------------------------------
inout(int[int]) test7709a(inout(int) bb) {
   int[int] r;
   r.keys;
   return null;
}
static assert(null == test7709a(2));
--------------------------------------------


Test case 2 (expected failure):
--------------------------------------------
inout(int[int]) test7709b(inout(int) bb) {
   int[int] r;
   r.sadjalsdjasldjasjs;
   return null;
}
static assert(null == test7709b(2));
--------------------------------------------


Both test cases cause segfault at template.c:4428 (TemplateInstance::semantic)
because 'sc' is null.

Duplicate of bug 7602?

> Duplicate of bug 7602?

I don't think so (at least on the surface). This variant of 7602 works (as
described in 7602's title):
--------------------------------------
string[] test7602b()
{
   int[string] array = ["2": 3];
   return array.keys;
}
enum str = test();
--------------------------------------

But this variant of 7709 fails:
--------------------------------------
inout(int[int]) test7709c(inout(int) bb)
{
   int[int] arr = [1: 2];
   arr.keys;
   return null;
}
enum str = test7709c(2);
--------------------------------------

Works now, on git head. I don't think this had anything to do with CTFE.
