We can't crash.
GetPaintServerPattern calls GetStopCount which will return 0 if there are no stop frames.
We only call GetStopInformation if GetStopCount > 0 and therefore we're guaranteed to get a frame.
Severity: critical → enhancement
Summary: crash [@ nsSVGGradientFrame::GetStopInformation] if !stopFrame → useless check of stopFrame in nsSVGGradientFrame::GetStopInformation
