Hi,

while I jumped forward and backward through the completions, Zsh crashed
with a coredump. I can't tell any more and I can't reproduce it.

```
% zsh --version
zsh 5.8 (x86_64-debian-linux-gnu)

% coredumpctl --debugger =gdb-bt-full debug

```

I still have the coredump. So, if you need any informations, I can extract
it.
