          Issue ID: 13424
           Summary: Initialization of delegate to do-nothing default
                    causes segfault at runtime
           Product: D
           Version: D2
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: critical
          Priority: P1
         Component: DMD
          Assignee: nobody at puremagic.com
          Reporter: hsteoh at quickfur.ath.cx

I have a struct of delegates that I'd like to default to do-nothing stubs:
------
struct S {
    void delegate(dchar ch) onChar = (dchar) {};
    ... /* other delegate variables similarly initialized */
}
------

It compiles, but crashes at runtime. Looking at the assembly code, it appears
to be attempting to call an invalid pointer.
