Hi.
Not sure if my code is correct - I wanted to build the simplest 
working example of simd use.  The following compiles and works 
under ldc (I have not disassessembled the result to see if it 
is using simd instructions), but generates a compiler error 
under dmd (2.066 and 2.067.0-b1 running under Fedora 20).

The only message is:

"Internal error: backend/el.c 2874"

Let me know if you think the code is okay, and if so I will see 
if I can figure out how to generate a bug report (if it's not 
something already known).

Thanks.

import std.stdio;
import core.simd;

void main()
{
        short8 vec;
        foreach(i;0..8)
        {
                vec.ptr[i]=cast(short)i;
        }
        vec=3*vec;
        foreach(i;0..8)
        {
                writefln("%s",vec.ptr[i]);
        }
}

It looks OK to me.

Whether or not the code is correct, any internal compiler error 
or segfault is a bug.
