Illegal hardware instruction when performing inner products

[jameskyle]

I can reliable crash julia with an illegal instruction error using the following:

julia> v1 = [1;-1;0;1;1]; v2 = [3;-3;2;5;5]; v3 = [5;1;3;2;8];
julia> (v2 .* v1) / (v1 .* v1)
[1]    69731 illegal hardware instruction  julia

[ihnorton]

versioninfo(true)?

On 0.3.3 and master, both, I get:

julia> v1 = [1;-1;0;1;1]; v2 = [3;-3;2;5;5]; v3 = [5;1;3;2;8];

julia> (v2 .* v1) / (v1 .* v1)

Ah, sorry, this is 0.3.2. Let me upgrade.

Sounds like staticfloat/homebrew-julia#130 (comment) ?

[jameskyle]

Recompiling according to static float/homebrew-julia#130 instructions.

[jameskyle]

All fixed!

Thanks!
