PHP Bug Type: Scripting Engine problem
Bug description: Calling functions through variables produces seg fault
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();
?>
