Bug 12604 – No "mismatched array lengths" error with narrowing conversions

With the code, the initialization of 'a' and assignment of 'b' will cause two compile time errors. void main() { int[1] a = [1,2,3]; int[1] b; b = [1,2,3]; } ---- test.d(3): Error: mismatched array lengths, 1 and 3 test.d(4): Error: mismatched array lengths, 1 and 3 But if you replace 'int' with 'short', the compile-time errors will disappear. void main() { short[1] a = [1,2,3]; short[1] b; b = [1,2,3]; } Instead runtime exception is thrown. object.Error@(0): Array lengths don't match for copy: 3 != 1
