Hi,
when indexing help page in info (after another index on another page was
already built), segmentation fault occurs. Steps to reproduce:
a) $ info info
b) hit "i" and then hit "RETURN" (you'll see index window)
c) hit "h" (you'll see help window)
d) hit "i" (you'll see Segmentation fault)
The problem is in do_info_index_search function within indices.c, where
the NULL pointer is accessed.
Patch bellow fixes the issue.
