Bug description: Crash When Calling Parent Constructor with call_user_func()
Description:
------------
If class B, extends Class A, and class B calls Class A's constructor in
its own contructor by using call_user_func("parent", "__construct"), and if
class A's constructor is defined as the class name rather than
"__construct", then PHP seems to crash (which results in Apache 2
crashing). Problem still exists with all extensions disabled.
Reproduce code:
---------------
<?php
class testClass
{
function testClass ()
{
echo 'Output string!';
}
}
class testClass2 extends testClass
{
function __construct ()
{
call_user_func(array('parent', '__construct'));
}
}
new testClass2;
?>
Expected result:
----------------
The above code should echo out the string 'Output string!'. This code
works correctly when "call_user_func" or "call_user_func_array" are not
used.
Actual result:
--------------
call_user_func() and call_user_func_array(), cause PHP and as a result,
Apache 2 to crash. When running PHP DBG debugger, the crash happens on the
execution of call_user_func() line. The Windows event log notes that
httpd.exe (apache) had crashed, blaming php5ts.dll for the fault.
