Weird engine problem

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?
