In the code below, if the visible IE is closed, whether by script or by the user, the bug manifests itself.  What will happen is that there will be a sequence of (ReadyState) 4's displayed while IE is extant.  When IE is closed, "Exiting" should be printed, but what happens is that a sequence of ReadyState=0's is printed, which is a bug.

The bug only happens if there are no instances of IE when the script is run.

The second instance of $ie has to be 'static'

Csaba Gabor from Vienna

Reproduce code:
// IE being closed doesn't terminate script
// if there are no IE instances on startup
$ie = new COM("InternetExplorer.Application");
$ie->visible = true;
$ie->Navigate2 ("about:blank");

$ie2 = new COM("InternetExplorer.Application");

try { while ($ie->ReadyState>=0) {
  print $ie->ReadyState;
  com_message_pump(200); } }
catch (com_exception $e) {}
print "Exiting";

Expected result:
I expect to see a sequence of 4s until I close IE, and then I expect to see Exiting printed

Actual result:
A sequence of 4s is printed, but when I close IE a sequence of 0s is printed which doesn't terminate till I use the windows task manager (ctrl+alt+delete) to kill the iexplore process.  (One could also use ctrl+C in the Cmd window, but that leaves a hidden IE instance, so the bug won't show itself next time around, until the IE is removed).

The bug manifests itself without user actions if
is inserted right above the 'try' line

If there is already an instance of IE in existence, then the bug does not happen.

The bug will also show itself if the '$ie2' line is replaced with:
function ieStatic() {
  static $ie;
  $ie = new COM("InternetExplorer.Application"); }
