--- Comment #10 from Paul "TBBle" Hampson Paul.Hampson@Pobox.com 2008-12-31 02:11:04 --- I've submitted a patch to fix the segfault as well: http://www.winehq.org/pipermail/wine-patches/attachments/20081231/428e5955/a...
With this patch and the patch linked in comment 9, the builtin winhttp works fine with the WAR patcher.
