Bug 2148 – Incorrect local closure detection when closure is used as local alias parameter

Check the following code: --- --- import std.stdio; template foo(alias magicFn) { int foo() { return magicFn(); } } int delegate() myfunc() { int num = 2; int nestedFunc() { return num; }; //return &nestedFunc; return &foo!(nestedFunc); } void main(string[] args) { auto dg = myfunc(); writeln("Dg result:", dg()); // prints garbage } ---- ---- Running this will print garbage, because the compiler thinks nestedFunc is a local closure (a closure that does not escape the enclosing scope), and thus will not allocate num on the heap.

My patch for bug 1841 fixes this. *** This issue has been marked as a duplicate of issue 1841 ***
