Many thanks for the report and the backtrace. I have tested this
with the recent development version and on the release branch and
the crash does not occur. I have tested it with Texinfo 7.0.1 and
the crash happened as you describe.
There was a fix for info since Texinfo 7.0.1 so this may have resolved
this problem. Hopefully we can make a Texinfo 7.0.2 release soon that
will include this fix.
