It used to work in 2.066.1; bisecting points to this PR:
https://github.com/D-Programming-Language/phobos/pull/3043

When bisecting between 2.066 and 2.067, there are other 
candidates:
https://github.com/D-Programming-Language/phobos/pull/3042
https://github.com/D-Programming-Language/dmd/pull/4459
https://github.com/D-Programming-Language/druntime/pull/1188

Unlikely:
https://github.com/D-Programming-Language/phobos/pull/3001
https://github.com/D-Programming-Language/phobos/pull/3043
https://github.com/D-Programming-Language/dmd/pull/4452
