588251 - fun.caller should throw if that value corresponds to a strict mode function (?)

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Jeff Walden [:Waldo]]

By my reading of 15.3.5.4 it looks like per ES5 this should pass:

  function nonstrict() { return nonstrict.caller; }
  function strict() { "use strict"; return nonstrict(); }
  try
  {
    strict();
    throw 17;
  }
  catch (e)
  {
    print(e instanceof TypeError ? "PASS" : "FAIL");
  }

Or am I missing something?

Easy two-ish-liner in fun_getProperty, just want to be sure I'm not misreading something.
