Bug 716338 turned on warnings-as-errors in content/html/content/src/Makefile.in
This breaks my local build (with --enable-warnings-as-errors), due to this build warning:
{
nsHTMLTableElement.cpp:709:12: error: variable ‘rv’ set but not used [-Werror=unused-but-set-variable]
}
Here's the lifetime of the variable in question:
> 679 NS_IMETHODIMP
> 680 nsHTMLTableElement::InsertRow(PRInt32 aIndex, nsIDOMHTMLElement** aValue)
> 681 {
[...]
> 709 nsresult rv;
[...]
> 738 rv = parent->AppendChild(newRowNode, getter_AddRefs(retChild));
[...]
> 743 rv = parent->InsertBefore(newRowNode, refRow,
> 744 getter_AddRefs(retChild));
[...]
> 780 rv = AppendChildTo(newRowGroup, true);
[...]
> 817 return NS_OK;
> 818 }
As the warning indicates, we set it a bunch of times but never bother to check it.
