No, it does not crash; it throws an exception what is something completely different. > This makes it impossible to pass arguments to COM functions that > require them to be passed by reference (MS Word's PrintOut > function, for example). That looks like a bad example, though, since according to the docs[1], the first parameter (Background) is not passed by ref.

This makes it impossible to pass arguments to COM functions that require them to be passed by reference (MS Word's PrintOut function, for example). (Tested in PHP 5.2.8 and 5.2.9rc2). Reproduce code: --------------- $var = new VARIANT(TRUE, VT_BOOL|VT_BYREF); Expected result: ---------------- Execution should continue, and I should be able to pass $var to a windows com function: EXAMPLE: $word = new COM("Word.Application"); $word->Documents->Open("mydoc.doc"); $var = new VARIANT(TRUE, VT_BOOL|VT_BYREF); $word->ActiveDocument->PrintOut($var); Actual result: -------------- PHP Fatal error: Uncaught exception 'com_exception' with message 'Variant type conversion failed: Type mismatch. ' in D:\test.php:1 Stack trace: #0 D:\test.php(1): variant->variant(true, 16395) #1 {main} thrown in D:\test.php on line 1 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=47401&edit=1
