https://bugs.winehq.org/show_bug.cgi?id=39028 Bug ID: 39028 Summary: Built-in iexplore crashes when opening forum/blog entries on hup.hu (crash in get_frame_by_name("yterr") Product: Wine Version: 1.7.48 Hardware: x86 OS: Linux Status: NEW Keywords: download, source Severity: normal Priority: P2 Component: mshtml Assignee: wine-bugs(a)winehq.org Reporter: gyebro69(a)gmail.com Distribution: --- Created attachment 51990 --> https://bugs.winehq.org/attachment.cgi?id=51990 terminal output HUP (Hungarian Unix Portal) is a Hungarian IT portal (not exclusively for Unix/Linux). The main page loads properly but opening the forums "fórumok" or blog pages "blogok" results in a crash shortly after the page was loaded.You can see the most recent forum posts on the main page, clicking on any of those links also triggers the crash. wine iexplore http://hup.hu/ Native IE (whether it is IE6 or IE7) when installed with winetricks works around the problem. wine-1.7.48-100-ge3c6777 -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Wine code on line 380 in mshtml/htmlwindow.c is: nsres = nsIDOMWindow_GetFrames(This->nswindow, &nsframes); if(NS_FAILED(nsres)) { FIXME("nsIDOMWindow_GetFrames failed: 0x%08x\n", nsres); return E_FAIL; } When viewing Gecko source code from https://github.com/mozilla/gecko-dev/blob/b6ea902b969546b6ae6c2d43e68b193bfb... on line 4129 the source of that function is: NS_IMETHODIMP nsGlobalWindow::GetFrames(nsIDOMWindowCollection** aFrames) { FORWARD_TO_OUTER(GetFrames, (aFrames), NS_ERROR_NOT_INITIALIZED); *aFrames = GetWindowList(); NS_IF_ADDREF(*aFrames); return NS_OK; } The definition of GetWindowList is in the same file (right before GetFrames): nsDOMWindowList* nsGlobalWindow::GetWindowList() { MOZ_ASSERT(IsOuterWindow()); if (!mFrames && mDocShell) { mFrames = new nsDOMWindowList(mDocShell); } return mFrames; } So as seen, there exists a chance that when mDocShell is NULL the GetWindowList will return also NULL (will not return any error codes). When viewing the same file for usage of GetWindowList() there seem to be NULL checks for it in Gecko source: void nsGlobalWindow::GetSupportedNames(nsTArray<nsString>& aNames) { FORWARD_TO_OUTER_VOID(GetSupportedNames, (aNames)); nsDOMWindowList* windows = GetWindowList(); if (windows) { ... nsDOMWindowList* windows = GetWindowList(); NS_ENSURE_TRUE(windows, nullptr); ... So all of it put together, to behave more like Gecko in this manner, Wine should also check for NULL nsframes. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
