Fixes #14250
This one is interesting. It looks like most likely this was caused by my PR #7127 that fixed other crash. After looking a bit more,
StarTypeis something old, and should never by used. At least I didn't findvisit_star_type()in any of the type visitors. Actually mypy already usesassert False, if we get to a non-special-cased star expression.Btw, I noticed that
pythonevaltest with empty expected output passes in case of a crash (at least on my machine), so I fix this too.
