reproducible segfault with composite type

[timholy]

I'm running with a fresh "make" after updating to commit 8574723.

Snip out the code below and save it as a file. Load that file into a julia session.

This next line seems to run properly:

img = MyType(imgdata,"drc",szv,[],ones(1,1),[],[],zeros(0),"");

But then if you type "img" on the julia command line you get a segfault:

img

However, the next version does not produce the segfault:

img = MyType(imgdata,"drc",szv,[],ones(1,1),["mm"],[],zeros(0),"");
img

Code:

type MyType{DataType<:Number}
    data::Array{DataType}
    arrayi_order::ASCIIString
    data_size::Vector{Int}
    arrayi_range::Vector
    arrayi2physc::Matrix{Float64}
    physc_unit::Vector
    physc_name::Vector
    arrayti2physt::Vector{Float64}
    t_unit::String
end

imgdata = rand(256,512,3)
sz = size(imgdata)
szv = vcat(sz...)

Fix is coming soon!

Wow, that is fast! Thanks for attending to this.

I was getting some crashes under other circumstances, too, but this fix seemed to have cured those, too. Many thanks!
