http://bugs.winehq.org/show_bug.cgi?id=58211 --- Comment #6 from Michael <micetym@gmail.com> --- Confirmed on plain (non-staging) Wine, on a different machine. Wine: wine-11.0 (vanilla, not staging) Distro: Ubuntu 26.04.1 LTS So this is neither a wine-staging artefact nor specific to the machine I reported from: my earlier reports were wine-staging 11.16, this one is a stock 11.0 release. The affected code is identical across the versions involved: wine-11.0 unguarded call at treeview.c:4406, assert at treeview.c:4555 master unguarded call at treeview.c:4472, assert at treeview.c:4621 else if (do_select) { TREEVIEW_ITEM *selection = infoPtr->selectedItem; /* Select the current item */ TREEVIEW_DoSelectItem(infoPtr, TVGN_CARET, ht.hItem, TVC_BYMOUSE); ht.hItem is whatever the hit test returned before NM_CLICK was dispatched to the application; nothing revalidates it afterwards. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
