Segmentation fault in makeinfo

[Jürgen Kahrs]

Hello,

I am currently writing some doc in the texinfo
format and I have a problem with a crashing makeinfo.
Usually, problems with makeinfo are my fault because
I am such an ignorant and dont use emacs to write the
files. But in this case I think there is a bug.

makeinfo --version
