Subject: Weird engine problem
From: sb@sebastian-bergmann.de (Sebastian Bergmann)

 For quite a while I have been fighting with what I believe to be a bug in
 the Zend Engine 2.

 In PHPUnit2 I have the following code:

   public function run(PHPUnit2_Framework_Test $test) {
       // $test->name: string(14) "testGetBalance"
       $this->startTest($test);

       try {
           // $test->name: string(14) "testGetBalance"
           $test->runBare();
       }

       catch (PHPUnit2_Framework_AssertionFailedError $e) {
           // $test->name: string(14) "testgetbalance"
           $this->addFailure($test, $e);
       }

       catch (Exception $e) {
           // $test->name: string(14) "testgetbalance"
           $this->addError($test, $e);
       }

       // $test->name: string(14) "testgetbalance"
       $this->endTest($test);
   }

 The object referenced by the variable $test has a private attribute
 called "name". The value of this attribute somehow get lowercased
 when the object is used inside the catch-block.

 My effort to come up with a small, reproducing script for this issue
 has yet to bear fruit as the obvious approach

   <?php
   class Foo {
       private $bar = 'BAR';
   }

   class Bar {
       public function doSomething(Foo $foo) {
           var_dump($foo);

           try {
               var_dump($foo);
               throw new Exception('...');
           }

           catch (Exception $e) {
               var_dump($foo);
           }

           var_dump($foo);
       }
   }

   $f = new Foo;
   $b = new Bar;
   $b->doSomething($f);
   ?>

 does not show the problem.

 Any idea what I might be missing here? Is there some way to debug the
 engine to see where the lowercasing happens?

 Thanks!
