Faulty code is here https://github.com/wine-mirror/wine/blob/master/dlls/uxtheme/draw.c#L232 where pRect is used with POINT size = {pRect->right-pRect->left, pRect->bottom-pRect->top}; without checking pRect as non-NULL (see the patch in attachment) -- Do not reply to this email, post in Bugzilla using the above URL to reply.
