From command line:

   dmd -run main.d

The OP code compilation segfaults with 2.062.

But with 2.063a (git head), compiler prints following error messages and occurs
no segfault.

phobos\std\algorithm.d(404): Error: function std.algorithm.MapResult!(adjoin,
Result).MapResult.back cannot get
frame pointer to adjoin
phobos\std\algorithm.d(438): Error: function std.algorithm.MapResult!(adjoin,
Result).MapResult.front cannot get frame pointer to adjoin
phobos\std\algorithm.d(450): Error: function std.algorithm.MapResult!(adjoin,
Result).MapResult.opIndex cannot get frame pointer to adjoin

What version do you use? The issue might be already fixed in git head.
