} Did you try --enable-zsh-{debug,mem{,-debug},secure-free}?
Yes; they produced no warnings, and of course the core dump didn't
happen even with nothing more than --enable-zsh-mem, so ...

No such luck. I still get a core dump.

Can you say a bit about why (and maybe add a comment to the code!)?

} It is half-intentional. When the current word for completion is requested
} from the lexer alias expansion is disabled for that word which is good and
} reasonable. The same mechanism is used by run-help.
I agree that alias expansion should be disabled for the current word; I
just think it should also be disabled for run-help no matter what word
is "current." For run-help's purposes only the word in command position
is interesting.
