Indeed, I can't reproduce the problem with 4.13a.dfsg.1-6

Recently we uploaded an updated package, which solves a crash issue
in info. Could you check that before we forward the problem to
upstream?

Thanks,

Yes, please run gdb on the binary, or create a core dump (ulimit -c 1)
followed by a run which crashed, and then run
gdb /usr/bin/info core
and send us the output.

I cannot reproduce it either ...

How to go from here? My next suggestion would be to request an gdb
trace and forward the problem to the texinfo maintainers.

I found another occurrence of this problem:
https://qa.mandriva.com/show_bug.cgi?id=32296 , which was closed as
"old bug".

The problem remains after upgrading:

$ LC_MESSAGES=C apt-cache policy libc6
libc6:
  Installed: 2.10.2-2
  Candidate: 2.10.2-2
  Version table:
 *** 2.10.2-2 0
100 http://ftp.be.debian.org unstable/main Packages
100 /var/lib/dpkg/status

I'm more than happy to provide any other input.

Cheers,
