Description:
------------
Hi,
I'm trying to connect over COM to standard .net and MS CAPICOM cryptography functions.

if i'm dismissing 20th line, i'm receiving warning "(null)(): Invoke() failed: The parameter is incorrect".

Then I tried to insert VARIANT with different types and receiving the same warning. But when I did VT_VARIANT, then Apache/2.0.47 restarted and log shows an error "[notice] Parent: child process exited with status 3221225477 -- Restarting."

When the same script was run on IIS/5 I received new warning "(null)(): Invoke() failed: No such interface supported in ..." on 19th line, while apache did understand this. Also other warning were as in apache.
When I tried to define value VARIANT as VT_VARIANT, I received warning "Warning: VT_VARIANT is invalid. Use VT_VARIANT|VT_BYREF instead. in c:\inetpub\wwwroot\crypt.php on line 50
PHP has encountered an Access Violation at 01914F48"

What's a matter?

BR,
Tauras
