Description Jerry Quinn 2010-04-17 13:23:00 UTC 
The following code should not compile but does with DMD 2.041.
The goto skips several initializations.

 void foo() {
    goto L0;
      int b;
      struct S { int a; this(int c) { a=c; } }
      S s = S(5);
      class C { int a; }
      C c = new C;
   L0: ;
      s.a++;
      c.a++;
 }

Is this the same as bug 602?

It's related.  There's an implicit init being accepted here.  However, there are 2 explicit inits being ignored as well, and bug 602 doesn't report that.

Another example:

unittest
{
      goto target;
      int x = 10;
      target:
      int y = x;
}

TDPL claims that that can't happen.
