The following code fails in DMD 2.059 but not 2.058. It fails on the pointer
arithmetic, and there's no separate pathway for CTFE.

int test()
    import std.algorithm;
    int[] arr1 = [10, 20, 30, 40, 50];
    int[] arr2 = arr1.dup;
    copy(arr1, arr2);
    return 35;

void main()
    enum v = test();

C:\D\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(5433): Error:
cast(int*)source and cast(int*)target point to independent memory blocks and
cannot be compared at compile time
main.d(15):        called from here: copy(arr1,arr2)
main.d(21):        called from here: test()
