[Bug 27340] New: WoW Launcher crashes, NULL pointer dereferenced
http://bugs.winehq.org/show_bug.cgi?id=27340 Summary: WoW Launcher crashes, NULL pointer dereferenced Product: Wine Version: 1.3.21 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: mshtml AssignedTo: wine-bugs(a)winehq.org ReportedBy: rankincj(a)yahoo.com This bug started happening at about the same time as the 1.3.21 release. What is happening is that the get_script_guid() function in dlls/mshtml/script.c is being passed nsscript=NULL. This function contains the line: nsres = nsIDOMHTMLScriptElement_GetType(nsscript, &val_str); where nsIDOMHTMLScriptElement_GetType() is really a macro defined as: #define nsIDOMHTMLScriptElement_GetType(This,aType) (This)->lpVtbl->GetType(This,aType) So being passed NULL for This is a "Bad Thing", obviously. I have no idea *why* nsscript is NULL suddenly; presumably doc_insert_script() is being passed NULL. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

So nsscript must still be NULL after calling nsISupports_QueryInterface(), and NS_FAILED(nsres) is not true.
That's not how QueryInterface is supposed to work. Either your assumption is wrong, or there's a bug in gecko (i.e., not in Wine.) I suspect the bug is elsewhere. Getting a backtrace with debug symbols would be more useful. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

According to my fprintf statements, nsscript is not NULL immediately before: if(nsparser) nsIParser_BeginEvaluatingParserInsertedScript(nsparser); in mutation.c, and is NULL immediately afterwards. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
