https://bugs.winehq.org/show_bug.cgi?id=16808 --- Comment #18 from Damjan Jovanovic <damjan.jov(a)gmail.com> --- The last thing logged before the crash is: 0009:fixme:treeview:TREEVIEW_EndEditLabelNow TREEVIEW_EndLabelEditNow in with no corresponding "out" logged. That calls the TVN_ENDLABELEDITW callback, which goes to: ON_NOTIFY_REFLECT(TVN_ENDLABELEDIT, OnEndLabelEdit) which is this method: void CPWTreeCtrl::OnEndLabelEdit(LPNMHDR pnmhdr, LRESULT *pLResult) In a +relay trace we see that execution re-enters comctrl32, calling TVM_SETITEMW and TVM_GETITEMW some time before crashing. That presumably comes from lines 626-628 in that method: SetItem(&ptvinfo->item); if (IsLeaf(ptvinfo->item.hItem)) { DWORD_PTR itemData = GetItemData(ti); Both return successfully, so the crash is somewhere later. The method is pretty long and calls other methods. It's a pity the application is so difficult to compile. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
