Package: zsh
Version: 4.3.0-dev-2-4
Severity: normal

Zsh segfaults when I am exploring the command history in a terminal
which is too small (number of lines) to show the multi-line command I
am looking at.

An example:

[24 line terminal]
% for a in b; do
for>    echo a
for>    echo ${a}
for>    echo b
for> done
a
b
b
%
[resize terminal to 3 lines]

If you now scroll back in the command history, Zsh will segfault.

The problem does not exist in zsh-4.2.5-7.
