Summary0000873: Crash viewing COM object properties in Eclipse PDT
Description

In Eclipse PDT, PHP crashes when a COM object is in scope.

Crash does not occur when Variables/Expressions is hidden, but still occurs when hovering over the COM object.

Whenever Eclipse tries to evaluate the object or expression in the debugger, PHP crashes.

Steps To Reproduce

On Windows, run a php script containing this, and step to the 2nd statement.

<?php
$conn = new COM('ADODB.Connection', NULL, CP_UTF8);

/* To crash PHP:

  • Hover over $conn->State
  • Open 'Variables' pane
  • Open 'Expressions' pane and watch $conn - value
  • shows as (Pending) then PHP crashes (attached png)
  • */

$state = $conn->State;
?>

Additional Information

Eclipse Juno Classic with installed PDT
PHP 5.4.5
Apache web server 2.2 + FCGID interface for PHP.

I have fixed this myself for now, by editing the com_dotnet extension, although the bug is in xdebug, and not com_dotnet.

zend_object_handlers.get_properties returns NULL in com_dotnet, which causes xdebug to crash.

Proof that this is a bug in xdebug:

<?php
$conn = new COM('ADODB.Connection', NULL, CP_UTF8);
var_dump($conn);
?>

Result without xdebug:
object(com)#1 (0) { }

Result with xdebug:
Internal Server Error/system exception (xdebug crashes PHP)

Script:
<?php
$conn = new COM('ADODB.Connection', NULL, CP_UTF8);
var_dump($conn);
?>

Outputs:
object(com)#1 (0) { }

When xdebug is loaded, PHP crashes. Unfortunately the issue has not been fixed in xdebug 2.2.5 on PHP 5.5 NTS VC11
