--- Comment #9 from Sebastian Lackner sebastian@fds-team.de --- I assume the easiest way to get rid of the HeapFree user callback would be something similar to http://source.winehq.org/git/wine.git/patch/577cb166d48e5c6f270237179cdbeb82.... Most likely Alexandre is already working on it, if not I'll write a patch during the next days.
