          Issue ID: 15232
           Summary: Escape analysis should be more sophisticated
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: timon.gehr at gmx.ch

Consider the following code:

void foo()@nogc{
    int x;
    struct S{ int bar()@nogc{ return x; } }
    S s;
}

Error: function foo @nogc function allocates a closure with the GC

No closure should be allocated here and in similar cases.
