Hi,
To reproduce, simply run "info --index-search=nh groff" using info from
texinfo 7.0.1 and the info pages from groff 1.22.4. info will
initialize the terminal, then the following will appear at the bottom
row:
> Found 'nh' in Request Index. (',' tries to find next.)
followed immediately by a message from inside glibc:
> malloc(): unsorted double linked list corrupted
Backtrace:
