Bug description: Calling restore_error_handler inside destructor crashes PHP
Description:
------------
This may be related to an older bug that was fixed (#24708) but I can
reproduce reliably (having spent days and hours chasing!). Basically, if
you call restore_error_handler from __destruct() things go horribly ary.
Interestingly enough, calling restore_exception_handler works just fine.
This happens both CLI and Apache 2.x.
Note that it does not matter if you use $this or &$this in the
constructor.
Reproduce code:
---------------
function __construct(
&$aConfig
)
{
if(is_array($aConfig))
{
$this->m_aConfig = &$aConfig; // Extraneous but it's in my
constructor.
set_error_handler(array &$this, "handleRuntimeException"));
set_exception_handler(array($this, "handleException"));
}
}
function __destruct()
{
//restore_error_handler();
restore_exception_handler();
unset($this->m_aConfig);
}
Expected result:
----------------
Proper ending of PHP script execution.
Actual result:
--------------
Segfault in php5ts.dll, ModVer: 5.0.3.3 Offset: 0004d661
