Hi.
While browsing documentation using "info", I've pressed some random
keys, and program caught SIGSEGV. After spending some time experimenting
I've learned that the key sequence was "-9-=". On my system, it generates
a fault every time and in any node. I'm using ASPLinux 7.1, kernel
2.4.10, glibc-2.2.2 and info 4.0. Gdb says only that fault is in
strcpy (). In cause you will not be able to reproduce this fault, I'll
try to compile program with debug info.
There are .spec file and patches used to build info in attachment.
Sorry for my bad english. Happy bughunting!

%description
Texinfo is a documentation system that can produce both online
information and printed output from a single source file. The GNU
Project uses the Texinfo file format for most of its documentation.
Install texinfo if you want a documentation system for producing both
online and print documentation from the same source file and/or if you
are going to write documentation for the GNU Project.
%package -n info
Summary: A stand-alone TTY-based reader for GNU texinfo documentation.
Group: System Environment/Base
# By making info prereq bash, other packages which have triggers based on
# info don't run those triggers until bash is in place as well. This is an
# ugly method of doing it (triggers which fire on set intersection would
# be better), but it's the best we can do for now. Talk to Erik before
# removing this.
Prereq: bash
%description -n info
The GNU project uses the texinfo file format for much of its
documentation. The info package provides a standalone TTY-based
browser program for viewing texinfo files.
You should install info, because GNU's texinfo documentation is a
valuable source of information about the software on your system.
