          Issue ID: 20922
           Summary: Cannot get frame pointer in templated member function
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: simen.kjaras@gmail.com

struct S {
    int i;

    void fun() {
        // Works fine
        outside!(() => i);
        // inside cannot get frame pointer to S.fun.__lambda2
        inside!(() => i);
    }

    void inside(alias fn)() {
        fn();
    }
}
void outside(alias fn)() {
    fn();
}

It seems more than a little counterintuitive that outside() can get a frame
pointer from S.fun() while inside() cannot. I expect both to compile.
