Bug description: PHP crashes in certain error scenarios
Description:
------------
In certain error scenarios, PHP crashes with an access violation instead
of reporting the error.
I have so far only identified one specific error that causes the crash,
but there may well be others.
Reproduce code:
---------------
$wmiLocator = new COM("WbemScripting.SWbemLocator");
$wmi = $wmiLocator->ConnectServer(".","root/MicrosoftDNS");
$a_rr = $wmi->Get("MicrosoftDNS_AType");
$a_rr->CreateInstanceFromTextRepresentation("","example.com","[*already
existent domain name*] IN A 127.0.0.1");
Expected result:
----------------
As indicated in the code, the crash only occurs when attempting to create
a domain record that already exists in the DNS server.
The functionally equivalent VBScript code reports a "Generic failure" when
the record already exists on the server.
Actual result:
--------------
Access Violation
