Reduced:

import std.container: RedBlackTree;
alias Container = RedBlackTree!(int, "a<b");

Error: [...]/std/container/rbtree.d(850): unittest failure

Lines 846-850:

         static if(less == "a < b")
             auto vals = [1, 2, 3, 4, 5];
         else
             auto vals = [5, 4, 3, 2, 1];
         assert(equal(r, vals));
