Rave-report beforeprint event memory leak

Question

I have this code in the event "DatabandBeforePrint" :

self.visible := not ((dvMatCommesseLavorazione.asstring = 'TAGLIO TRONCATRICE')
  or (dvMatCommesseLavorazione.asstring = 'TAGLIO SEZIONATRICE')
  or (dvMatCommesseLavorazione.asstring = 'TAGLIO PANTOGRAFO') );

When I close the application, why do I get a "Memory leak" from madexcept. memory leak

Is there anyone that could explain me why this occurs?

Thanks for any helps.

I think this occurs because Rave vs Delphi WideString issues. You can workaround it adding and filling a boolean or integer field according your business rule. Checking an integer or boolean field would avoid WideString comparison. I read somewhere that new versions of Rave does correct this issues.
