Bug 10282 – Refused assignment of vector op result to const array

struct Foo { double[1] x; } void main() { Foo[] foos; foreach (f; foos) const double[1] a = f.x[] - f.x[]; } DMD 2.064alpha gives a not meaningful error message with no line number: Error: cannot modify const expression p2[p]

Now the error message is fixed: test3.d(7,25): Error: invalid array operation 'a[] = f.x[] - f.x[]' for element type const(double) Some more examples: void main() { int[3] a1 = [1, 3, 6]; int[3] a2 = [1, 3, 6] * 3; // OK const int[3] a3 = a1[] * 3; // Error const int[3] a4 = [1, 3, 6] * 3; // Error immutable int[3] a5 = [1, 3, 6] * 3; // Error } dmd 2.067alpha gives: test.d(4,22): Error: _arraySliceExpMulSliceAssign_i (int[] p2, int c1, const(int[]) p0) is not callable using argument types (const(int)[], int, int[]) test.d(5,22): Error: _arraySliceExpMulSliceAssign_i (int[] p2, int c1, const(int[]) p0) is not callable using argument types (const(int)[], int, int[]) test.d(6,22): Error: _arraySliceExpMulSliceAssign_i (int[] p2, int c1, const(int[]) p0) is not callable using argument types (immutable(int)[], int, int[])
