The array is not relocated. You can check by comparing the pointers: ---- void main() { int[] arr; arr.length = 7; int* p = arr.ptr; arr.length = 6; assert(arr.ptr == p); /* passes */ } ---- I'm changing the title of this issue accordingly. -- |

https://issues.dlang.org/show_bug.cgi?id=15481 --- Comment #2 from Valentin Milea <valentin.milea@gmail.com> --- Maybe the reallocation function is called and returns the same buffer. But why call it in the first place, if reducing array length is supposed to be _equivalent_ to slicing? -- |
