In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better.

Previous Comments: ------------------------------------------------------------------------ [2003-11-28 09:24:52] wez@php.net I'm lazy and I didn't see where to download your sample delphi COM object. Could you please email me a .zip of the smallest possible Delphi 5 project + short php script that will reproduce this crash? (I have Delphi 5, so just the source code will do). ------------------------------------------------------------------------ [2003-09-25 19:07:22] blomster at algonet dot se Description: ------------ To me it seems all COM objects written in Delphi 5 crashes PHP - fully reproducible. I don't know about Delphi 6 or 7. These objects work in VBScript, Javascript, Perl, Word/Excel VBA macros, and more. Applies to PHP 4.3.3 but also to PHP 5 downloaded 24 sept 2003. An example, which I have not written myself: http://www.undu.com/Articles/000928g.html I can compile that source and mail the dll to anybody willing to test. I have more examples, including my own Delphi COM object. I recognize the description in bug #25586 - this has also happened to me and I believe it's related to what I describe here. That was Delphi 6. A bizarre workaround was found for my own COM object: If I override Delphi's own GetTypeInfo, and always return HRESULT -1, then PHP continues by calling other methods and does not crash, but then I instead get a memory leak. I have not understood how the crash and the leak are related, if at all. Thanks for any assistance & best regards Jens Blomster Uppsala, Sweden Reproduce code: --------------- From the above-mentioned message board COM example: $instance = new COM("msgboard.MessageBoard"); $i = $instance->CreateMessage("hej","hopp","i baljan"); Expected result: ---------------- The message created in the COM object, just like it does in VBScript. Actual result: -------------- A PHP crash. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25664&edit=1
