https://issues.dlang.org/show_bug.cgi?id=20042 Issue ID: 20042 Summary: __vector CTFE crashes the compiler 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 Vec4 { __vector(float[4]) raw; this(const(float[4]) value...) inout pure safe nothrow nogc { __vector(float[4]) raw; raw[] = value[]; this.raw = raw; } } void main() { static immutable Vec4 v = Vec4( 1.0f, 2.0f, 3.0f, 4.0f ); static foreach(d; 0 .. 4) write(v.raw[d], " "); } Attempting to compile the above yields "Illegal instruction (core dumped)". Removing the `static immutable` makes everything work as expected. --
