Yes, that copy assignment operator should not be necessary. However,
I've fixed this[1] by adding the matching copy constructor. From the
commit message:

"Instead of adding the copy constructor we could have also dropped the copy
assignment since it is identical to what would be implied. It's not, however,
clear why it was added in the first place (it was added before we started
tracking development with git). Chances are, some old and broken compiler is
confused by the other assignment operator. So to be on the safe side we
rather add the copy constructor."

3.2.0 is the latest official release. There are some pre-release
snapshots[2] but they don't include this fix. The easiest is
probably just to patch your copy of 3.2.0.
