wine users - Oct 2001 - IAdviseSink_QueryInterface (datacache)

Hi all,
I'm working on an nt40 program under Wine.
It works well using the Microsoft's OLE32, but we *absolutely* need it 
to work without it.

I'm using the 2001-07-31 release of wine, and the program crashes little 
after starting, inside the DataCache_GetAdvise function (in 
datacache.c),  on the instruction:

  IAdviseSink_QueryInterface(this->sinkInterface,
                   &IID_IAdviseSink,
                   (void**)ppAdvSink);
 
I tried to find out the problem, but the source is really hard to read, 
since it uses macros defined around other macros around other macros and 
so on. I only understood that the structure this (created by the macro 
_ICOM_THIS_From_IViewObject2(DataCache, iface) ) is corrupted.

Does anybody know the bug?

Can anybody tell me if there's at least an explanation on the 
datacache.c file?

thank you
