Code: ------ int delegate() globDg; void func(scope int delegate() dg) { globDg = dg; globDg(); } void sub() { int x; func(() { return ++x; }); } void trashme() { import std.stdio; writeln(globDg()); // prints garbage } void main() { sub(); trashme(); } ------

The line "globDg = dg" should be rejected at compile-time, but isn't.
