Subject: [BUG] Zsh crashes when using autocomplete because of memory unsafety (double free)
Date: Fri, 26 Jun 2020 17:03:03 +0200 [thread overview]
Message-ID: <00cb28e8-004e-2c8c-e02d-6063f4079c1d@soptik.tech> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 1156 bytes --]
Note: I'm using ohmyzsh to provide autocomplete and I can't reproduce it
without ohmyzsh, but since ohmyzsh is written entirely in shell, this
should be an issue in zsh itself.
When I trigger autocomplete in one position, zsh crashes, yielding one
of the following messages, seemingly at random:
(none, zsh crashes silently) x12
double free or corruption (out) x5
Zsh crashed each time I tried it.
zsh 5.8 (x86_64-pc-linux-gnu)
ohmyzsh, commit 6152ac30bede172ba0422a8610dc796948ae1546
Minimal setup:
$ alias a='""'
^
Place cursor so it stands on the first " character and press Tab to
trigger autocomplete. Zsh crashes.
I have almost default ohmyzsh installation, the only thing I changed is
theme (to `mrtazz`) and `git` plugin, none of which should affect this.
Zsh config itself (after being modified by ohmyzsh) is unchanged, if one
doesn't count `PATH` exports. Thus I don't see the need to attach my
full config. If anyone has troubles reproducing this, let me know. But
it should be enough to have ohmyzsh installed.
