StackOverflowError when assigning Array{Array{Float32, 3}, 1} in version 0.5 rc3

[Uri Patish]

Hi,

I came across the following issue while using version 0.5 rc3,

julia> a = Array{Array{Float32, 3}, 1}(2) 

2-element Array{Array{Float32,3},1}:

 #undef

 #undef

julia> a[1] = rand(Float32, 2, 2, 2)

ERROR: StackOverflowError:

julia> b = Array{Array{Float64, 3}, 1}(2)

2-element Array{Array{Float64,3},1}:

 #undef

 #undef

julia> b[1] = rand(Float64, 2, 2, 2)

2x2x2 Array{Float64,3}:

[:, :, 1] =

 0.146411  0.354293

 0.672552  0.491225

[:, :, 2] =

 0.0184464  0.0200675

 0.656842   0.957667

This error doesn't occur in version 0.4.6. In addition, it doesn't happen unless the dimension of the inner array is less than 3.

Do you have packages loaded?

(Probably unrelated but) what platform?

Does the stackoverflow error come with any backtrace at all?

What's `@which convert(Array{Float32,3}, rand(Float32, 2, 2, 2))`?

[Uri Patish]

Windows machine, and no backtrace.

Should I open I bug in github?

Probably yes. But I can't reproduce this either. Maybe you should
answer Yuyichao's questions first:

>> Do you have packages loaded?

(My question: this happens with a freshly started REPL?)

[Uri Patish]

No packages loaded, window 8.1, and no backtrace.

Yes, from a freshly started REPL.

I also can't reproduce with RC4? Could you try to see if you can reproduce with RC4?
