Hey all,

there appear to be some crashes when using the source command in the
precmd function.

It only happens in zsh 4.3.10, zsh 4.3.9 works fine.
So far, it could be reproduced on various Linux distributions (Gentoo,
Debian, Ubuntu), FreeBSD and OpenBSD.

Steps to reproduce:
Write
> precmd () { source somefile }
into .zshrc
Then
> touch somefile
(so it exists, does not need to have any content)

Then start zsh and hit return.

The first attachment is the glibc backtrace I get, the second attachment
a gdb backtrace by someone else.
