void swap(int[]* lhs, int[]* rhs) { *lhs = *rhs; *rhs = *lhs; } int ctfeSort() { int[][2] x; swap(&x[0], &x[1]); return 0; } void main() { enum x = ctfeSort(); } Causes a stack overflow with dmd master (2.054) The same thing happens when using references. void swap(ref int[] lhs, ref int[] rhs) { lhs = rhs; rhs = lhs; } int ctfeSort() { int[][2] x; swap(x[0], x[1]); return 0; } void main() { enum x = ctfeSort(); }
