Smart Pointer and Access Violation

[TSYS]

I have a problem - I think - that's driving me crazy. I have a smart pointer declared as follows:

#import "C55 Library.dll" no_namespace
  IDecodeC55Ptr    pDecodeC55;

I create the COM object within my InitDialog procedure:

  HRESULT hr = pDecodeC55.CreateInstance( __uuidof( DecodeC55 ) );

When I use the debugger to step through this, I get an error message twice: "First chance exception in junk.exe (NTDLL.DLL): 0xC0000005: Access Violation"

The thing is that CreateInstance then returns S_OK, and the library does get loaded.

Can anybody shed some light on what's going on here? And whether or not I should be worried?
