Internal compiler error using lambdas

[npadmana]

Summary of Problem

I'm running into an internal compiler error (CAL1184) trying to pass a lambda to a function.

Steps to Reproduce

Source Code:

proc times2(f) {
  return 2*f();
}

proc test(k : int) {
  var func = lambda() { return k;};
  writeln(times2(func));
}

test(2);

Compile command:
chpl buggy2.chpl

Compile output:

buggy2.chpl:1: In function 'times2':
buggy2.chpl:2: internal error: CAL1184 chpl Version 1.14.0.2a61e6e

Internal errors indicate a bug in the Chapel compiler ("It's us, not you"),
and we're sorry for the hassle.  We would appreciate your reporting this bug --

the filename + line number above may be useful in working around the issue.

@jabraham17 Now that you mention it (in #6538) the code here no longer hits an internal error, but instead reports the same sort of error as in the .good file there,

buggy2.chpl:5: In function 'test':
buggy2.chpl:6: error: cannot capture lambda because it refers to outer variables
buggy2.chpl:6: note: such as 'k', here
