Summary of Problem

A particular pattern of code leaks memory when it should not. I've verified that this leak existed in 1.24.

Steps to Reproduce

Source Code:

// tt.chpl

class MyArgument {
  var x: int;
}
record myParser {
  var y: int;
}

proc myParser.addHandler(i: int) throws {
  return new shared MyArgument(i);
}

proc callAddHandler(ref parser) throws {
  // does not leak
  //var tmp = parser.addHandler(1);

  // leaks
  parser.addHandler(1);
}

proc main() {
  try! {
    var parser = new myParser();
    // does not leak
    //parser.addHandler(1);

    // leaks
    callAddHandler(parser);
  }
}

Compile command:
chpl tt.chpl

Execution command:
./tt --memLeaks
