Subject: PATCH: fix for SEGV
Date: Tue, 24 Aug 1999 14:16:18 +0200 (MET DST) [thread overview]
Message-ID: <199908241216.OAA09744@beta.informatik.hu-berlin.de> (raw)
Try this:
...) ./zsh -f
% setopt autocd; hash wc=/bin/wc; echo|wc
It'll give you a SEGV in `isreallycom()', trying to look at
`cn->u.name' which isn't set because for hashed commands `cn->u.cmd'
is used.
Bye
Sven
