Subj : [Rhino] infinite loop when compiling with optimization

Hi,
I have some legacy code that gets the Rhino compiler in a infinite loop when
compiled with -opt greather than zero, for example this file:

------------------------------------------
// infloop.js
function infLoop(inStr) {
  var i = -1;
  while ((i = inStr.indexOf("%")) != -1) {
    inStr = inStr.replace("%", "");
  }
  return inStr;
}

var str = infLoop("abc%def");
------------------------------------------

I know that the function can be written in one line with regular
expressions, the example is only to demonstrate the problem in the
optimizer.
I have tested with 1_5R5 and 1_6R1 and they hang the same way.
Let me know if you want me to submit a bug.

Mike
