Apache crashes if I use the return value from a function in a SimpleTest test case

Question

When I run the following test case in simpletest, Apache crashes if I use line B, but everything works if I use line A.

class TestPredicateRequest extends UnitTestCase { function testConstructWithPredicate() { Mock::generate("IQueryRequest"); $oRequest = new MockIQueryRequest(); $oPrototype = new QueryPrototype("TEST_COMMAND_STRING", array(1 => QueryTypeConstants::CHARACTER_ID, 2 => QueryTypeConstants::CHARACTER_ID), QueryTypeConstants::BOOLEAN); $oRequest->returns("GetArguments", array(2 => 102)); //only argument 2 is set. $oRequest->returns("GetPrototype", $oPrototype); $oRequest->returns("GetUnsetArguments", array(1)); //only argument 1 is unset $oToTest = new CharacterPredicateRequest($oRequest); $this->Here(101); //LINE A //$oItem = $this->Here(101); //LINE B } function Here($CharacterID) { return $CharacterID; } } 

What possible reason would be that storing the return value of the function or not determines whether an error occurs?

Additional Information:

If I throw an exception after line A or line B, the exception bubbles up and I get a page with error results, if necessary. This tells me that for some reason, Framework SimpleTest doesn't like the case with line B. Is it because it has no statements?

Update x2:

The error log file from Apache seems pretty useless:

Answer 1

perhaps because you have limited memory access for B use set_ini () for -1 at the top of your page to use unlimited resources.
