Bug#598932: /usr/bin/info segmentation fault

[Sergio Gelato <Sergio.Gelato@astro.su.se>]

Package: info
Version: 4.13a.dfsg.1-5

(Problem originally observed on lenny, with info 4.11.dfsg.1-4, both i386
and amd64 platforms; confirmed on squeeze i386.)

The info command reproducibly segfaults when viewing a certain (possibly
corrupt, but still...) info file.

To reproduce, get /usr/share/info/accounting.info.gz from version 6.4~pre1-6
of the acct package. This is the version in lenny; I was unable to reproduce
the segfault with the corresponding file from acct 6.5.4-2 which is currently
in squeeze.

Then run "info accounting", navigate to the menu entry for dump-acct, and
hit Return.

Programs should not crash in the face of unexpected data, so this is a bug
in the info command. (There may also be, or have been, a problem in the
acct package but that's another story.)
