Description:
------------
An assignment (of a class variable?) in a switch statement causes an
apache crash. The first object instantiation int eh attached sample
($testval == 1) succeeds; the second one ($testval == 2) fails.
Reproduce code:
---------------
<?php
class TestClass
{
var $type;
function TestClass($testval)
{
$type = intval("2");
if ($testval == 1)
{
switch($type)
{
default:
echo "Test 1 worked<br>";
flush();
break;
}
}
else if ($testval == 2)
{
switch($this->type = $type) /* This line causes crash
*/
{
default:
echo "Test 2 worked<br>";
flush();
break;
}
}
}
}
$tc = new TestClass(1);
$tc = new TestClass(2);
?>
Actual result:
--------------
In apache/error.log:
[notice] child pid XXXXX exit signal Segmentation fault (11)
