simd and dmd compiler v 2.066 and 2.067.0-b1

[Laeeth Isharc via Digitalmars-d-learn]

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.


Laeeth.

         {
                 writefln("%s",vec.ptr[i]);
         }
