Re: [BUG] Zsh crashes when reverse-menu-complete is invoked during complist MENUSELECT without 'menu:' in $compstate[insert]

It calls reversemenucomplete() which is a function that pre-dates menu
selection. The path down which it clears minfo didn't look appropriate
from within menu selection. But it doesn't crash for forward menu
completion. Taking the same code path as for forward completion but
with zmult negated appears to work fine and would seem logical enough.
But perhaps there's some aspect to reversemenucomplete() that would be
needed so it'd be good if this can get some further testing.
