--- Comment #4 from kugan at gcc dot gnu.org ---
In the loop here, the value defined in the loop (e) is used outside the loop
hence this should not be detected as popcount (AFIK). I will have a look at
fixing this.

It seems that kugan wrote the revision that broke it, but the bug is
unassigned.

I'd be interested to find the process to re-assign.
