 Fascinating indeed.  If someone can bisect where during 4.4 development we
 fixed this again or where during 4.3 development we broke it that would be
 nice.

This test case was fixed for 4.4 by r142961, the fix for PR38564.

This test case fails with a recent 4.3, but r142961 applies cleanly and fixes
the test case. I haven't done any testsuite runs on that combo yet, however.

It's also fixed on mainline and it works on 4.2.1. I don't have a version of
4.3 lying around, but that would be the only open branch which appears to
still have the problem.

Would someone mind testing this on a current 4.3.x?

fails with 4.3.4, I don't have a 4.3 branch to check the tip

 pr.cc:38: error: invalid operands of types #8216;bool#8217; and 
 #8216;int#8217; to binary
 #8216;operator==#8217;

This is doubly fascinating as there is no operator== in this line ;-)
