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.
