--- Comment #11 from Sam James <sjames at gcc dot gnu.org> --- I'm not sure what to do next. I can write up instructions for reproducing it manually w/ a full Firefox build, but that doesn't help much. I know I need to identify some training input but FF is itself huge and trains itself on many tests. How do I break this down into something manageable?
