(In reply to Tyler Wilcock from comment #3) > Created attachment 467243 [details] > Patch --- a/Source/WebCore/accessibility/mac/WebAccessibilityObjectWrapperMac.mm +++ b/Source/WebCore/accessibility/mac/WebAccessibilityObjectWrapperMac.mm + auto attributedString = backingObject->attributedStringForTextMarkerRange(backingObject->textMarkerRangeForNSRange(range), AXCoreObject::SpellCheck::Yes); + if (![attributedString length]) + return nil; + + return attributedString.autorelease(); Looks good, just consider the 2 liner: auto attributedString = backingObject->attributedStringForTextMarkerRange(backingObject->textMarkerRangeForNSRange(range), AXCoreObject::SpellCheck::Yes); return [attributedString length] ? attributedString.autorelease() : nil;
