          Issue ID: 13861
           Summary: compiler segfault with nested struct, cannot access
                    frame
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: critical
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com
          Reporter: vlevenfeld gmail.com

This code does not compile:

struct Foo (alias f, T)
{
    void bar () {} // BUG if not commented out, I get "Error: cannot access
frame pointer of test.N.Foo!((n) => n, ulong).Foo"
}

void main () {
    auto A = N;
    typeof (A) x;
}

static N () {return Foo!(n => n, size_t)();}

In addition, when I attempt to use the value of A instead of just taking the
typeof, I get a compiler segfault. Here is the backtrace:
