Details

I went to http://bugzilla.mozilla.org/ and entered a bug number (9804) into the "Find bug #" dialog. When I pressed the Find button I got this SIGSEV from mozilla. I was running this on a RedHat 5.2 system (Linux-Intel) form the CVS Fri Nov 4. The code in question is here (layout/html/forms/src/nsListControlFrame.cpp Line 1115) 1111 nsIDOMHTMLSelectElement* 1112 nsListControlFrame::GetSelect(nsIContent * aContent) 1113 { 1114 nsIDOMHTMLSelectElement* selectElement = nsnull; 1115 nsresult result = aContent->QueryInterface(nsCOMTypeInfo<nsIDOMHTMLSelectElement>::GetIID(), The problem is that the aContent pointer is NULL so it creates a SIGSEV. #0 0x40e76dd2 in nsListControlFrame::GetSelect (aContent=0x0) at ../../../../../layout/html/forms/src/nsListControlFrame.cpp:1115 #1 0x40e76f4e in nsListControlFrame::GetOptions
