Bug 7898 – [CTFE] std.algorithm:copy fails when used with two arrays

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()

Upgraded to regression.

The workaround is unnecessary now that 8216 CTFE should allow 'pointer is inside range' comparisons has been implemented in the compiler. https://github.com/D-Programming-Language/phobos/commit/8d8f109e06583c99333a348385bd9abae6ae071d Merge pull request #700 from donc/undo7898workaround Undo workaround for bug 7898
