The straightforward fix to avoid this out-of-array access was my first patch at http://www.winehq.org/pipermail/wine-patches/2007-September/044612.html which you didn't like too much ;-), so I cooked up the second one http://www.winehq.org/pipermail/wine-patches/2007-November/047288.html Do you (or does anyone else) have a better idea how to address this?
