https://issues.dlang.org/show_bug.cgi?id=20041 Issue ID: 20041 Summary: CTFE incorrect result with __vector Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: major Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: thomas.bockman@gmail.com import std.stdio; struct Vec3Fast { __vector(float[4]) raw; this(const(float[3]) value...) inout pure @safe nothrow @nogc { __vector(float[4]) raw; raw[0 .. 3] = value[]; raw[3] = 0.0f; this.raw = raw; } } void main() { static immutable Vec3Fast v = Vec3Fast( 1.0f, 2.0f, 3.0f ); static foreach(d; 0 .. 4) write(v.raw[d], " "); } With CTFE, the above prints "nan nan nan nan ", which is wrong. If I remove the `static immutable`, it prints "1 2 3 0" as it should. -- |
