https://issues.dlang.org/show_bug.cgi?id=13775 Issue ID: 13775 Summary: Broken explicit casting of dynamic array slices of known size to static array of different type Product: D Version: D2 Hardware: All OS: All Status: NEW Keywords: ice, rejects-valid Severity: regression Priority: P1 Component: DMD Assignee: nobody puremagic.com Reporter: verylonglogin.reg gmail.com This code used to compile: --- void main() { ubyte[4] ubytes; byte[2] bytes = cast(byte[2]) ubytes[0 .. 2]; } --- main.d(4): Error: e2ir: cannot cast ubytes[0..2] of type ubyte[] to type byte[2] --- In case it was an accept-invalid bug, what is the reason to disallow the feature and break user code without any deprecation message and with such unpleasant minor ICE message? --
