Subject: core dump in vichange()
Date: Thu, 13 Mar 2014 21:31:59 +0900 [thread overview]
Message-ID: <83FCB166-FC90-4A7A-80A2-6A0420FFA87A@kba.biglobe.ne.jp> (raw)
The following causes a core dump in function vichange():
$ zsh -f
$ bindkey -v
$ echo foo
$ <ESC>kcw
k=up-line-or-history, c=vi-change, w=vi-forward-word
(or 'kc' followed by any motion command)
The core dump is at line 404 of zle_vi.c:
vistartchange = curchange->prev->changeno;
with curchange->prev == NULL.
