description:
Enlarge the set_status[] array by a single element

In the get_and_unpack_sets() function there is accessed the
set_status[SET_GROUP_END] element in the array. The array is allocated on
the stack with SET_GROUP_END elements. This means that it is 1 element too
short.

This has been reported with MKSANITIZER=yes with Address Sanitizer.
