#29668 [NEW]: Memory leak when looping an associative array

From: thecanadiancrappler at hotmail dot com Operating system: Windows XP SP 1 PHP version: 4.3.8 PHP Bug Type: Reproducible crash Bug description: Memory leak when looping an associative array Description: ------------ When looping numerically through an associative array, certain operations cause a massive memory leak in Apache, eating up all available ram at about 60mb/s. Windows grinds to a halt as 1gb of Virtual Memory is gobbled up. Trying to echo each element of the array returns nothing as would be expected, but concatting or executing a function such a stripslashes on the elements causes the memory leak. My php.ini differs only in max_execution time and the maximum size of POST uploads. Reproduce code: --------------- $array['a'] = 'Some text'; $array['b'] = "It\'s nice text"; // prints 2 echo count($array); // prints nothing echo $array[0]; // does nothing $array[0] = stripslashes($array[0]); for ($i=0; $i<count($array); $i++) { // does nothing echo $array[$i]; // memory leak $array[$i] = 'blah' . $array[$i]; // memory leak $array[$i] = stripslashes($array[$i]); } Expected result: ---------------- To have no effect on the array Actual result: -------------- Sorry, I can't decipher your instructions for using backtrace!
