Reduced test case. Running ng.bat will reproduce link-failure.

Sorry I was wrong. The issue commit that was introducing the change was in
Phobos repository.

https://github.com/D-Programming-Language/phobos/commit/a9d45235da6509e21450dea1825a5fa1dff9eed4#diff-54cf8402b22024ae667d4048a5126f0eL17

The commit has removed `import std.string;` from the module level scope in
std.array. Unfortunately it triggered a previously unknown forward reference
bug in compiler.

See also the minimized test case I attached.
