hi all,

as i wrote few days ago, there's a problem with the DataCache_GetAdvise
function in dlls/ole32/datacache.c:
the call

(this->sinkInterface)->lpVtbl->QueryInterface(this->sinkInterface,  
                                                                        
        &IID_IAdviseSink,  
                                                                        
        (void**)ppAdvSink);

crashes since this->sinkInterface is NULL.

executing the program with the --debugmsg +relay option i've seen
that there are no calls to DataCache_SetAdvise before this call, the
sinkInferface field is not initialized.

but the program works well under M$window$.

looking here and there in the source, i tried to replace this call with

this->lpvtbl2->QueryInterface(this->lpvtbl2,  
                                                     &IID_IAdviseSink,  
                                                     (void**)ppAdvSink);


i don't know why, but it works.

ok, what should i do now to let the world know this?

thanks
