Compiler crash with static ubyte16 definition

[mleise]

import core.simd;
static ubyte16 v = ['a','a','a','a','a','a','a','a','a','a','a','a','a','a','a','a'];

This crashes the compiler (LLVM 3.3) for me on Linux x64:

Crashes LDC head and LLVM 3.4 trunk, too.
The Type * value passed to stripModifiers() is 0.

The vector type is not considered in DtoConstArrayInitializer(). This results in a null value for elemty which causes the crash.

What's the recommended way to use a ubyte16 vector of a compile-time known scalar at the moment?
As far as I can tell the fastest option is to have one "prepared" somewhere in the data segment of the program, but I need at least the flexibility to create them during CTFE. So I wrote a template that would declare static, immutable ubyte16's and ran into this and also another problem about cast(vector)cast(ubyte)0u not being const. But I'll first look and see if this already fixes it.

Well, currently I can't recommend something. But your approach looks reasonable to me.

The const problem looks a bit like http://d.puremagic.com/issues/show_bug.cgi?id=10312.
