605891 - Wrong (?) bytecode for local functions within try blocks.

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Brian Hackett [Laid off!]]

var f;
function test(length)
{
  try
  {
    function f() { }
    f();
  }
  catch(ex)
  {
    print("Threw " + ex);
  }
}
test();

This gives me:

TypeError: f is not a function

V8 and JSC don't throw, which looks like the right behavior to me.  If I disassemble the bytecode, the access to f is a CALLGLOBAL, as if the local is not in scope.

This is bug 584603, I think.

No longer reproducible, probably fixed when the new block-Level Function declaration semantics were implemented. Resolving as WFM.
