I think this patch is responsible for PR 15641. The testcase from the PR works with a gfortran compiled before your change (May 19th), and the only ChangeLog entry which seems to affect this is this one.

Your patch assumed that the items in a segment were sorted. I've modified you patch so that condition is maintained while building the segment.

I also tidied up the way we built the equivalence chains. The algorithm is still O(something nasty), but hopefully a much smaller O ;)

Tested on i686-linux. Applied to mainline.
