If I try to call a function from a class and the name of the function is inside a variable php seg faults.
It works fine with php 4.2.3 and if the function isn't inside a class. Some pear script which use this don't produce a crash but give errors about an undefined function with a numeric name. (e.g. Fatal error: Call to undefined function:  138421340() in /usr/lib/php/PEAR.php on line 512)

Example:
<?php
class bugtest {
        function bug() {
                echo "test\n";
        }
}

$test = new bugtest();
$test1 = "bug";
$test->$test1();
?>
