Thanks for the bug report. I reproduced the problem with texinfo and installed the attached Gnulib patch, which fixed things for me with texinfo. I didn't quite follow the 'nano' instructions but I hope this fixes the problem there too.

As this is a glibc bug I filed a bug report there too:


and I'll try to make sure it gets fixed there too.
