zsh seg fault when TERM = linux

[Murilo Opsfelder Araújo <mopsfelder@xxxxxxxxx>]

Hi zsh workers,

I'd like to report a situation for you.

I'm trying to connect in a ssh server with a user using zsh as your
default shell but zsh crashes.

In following, there are some info. If you need more, please, feel free to ask.

TERM env var on client side is set to 'linux':

client$ echo $TERM
linux

On the server I changed the user's shell to csh:

server$ echo $SHELL
/bin/csh

When logged in on server I tried to run zsh:

server$ zsh
Segmentation fault
Exit 139

I tried a gdb with zsh. See the results:

server$ gdb zsh

Does gdb seem to be OK?

To resolve the problem I rollbacked user's shell to zsh on server side
and did a env TERM=xterm on client side. See:

client$ env TERM=xterm ssh remoteuser@server
Password: *******
server$

So, I don't know if this situation is a bug or a conf problem. Feel
free to ask more information.

Thanks in advance.
