[julia-users] drandn sometimes crashes

[Antonio Suriano]

addprocs(3)

@everywhere using DistributedArrays

function tony(N)
return sum(drandn(N,N))
end


function pesante(N)
a=zeros(N,N)
for i = 1:N
for j=1:N
a[i,j]=tony(1000)
end
end
return a
end

matrice= pesante(100)


----
julia 0.4.1

when calling pesante with N>30 sometimes it crashes

LoadError: BoundsError: attempt to access 0-element Array{Any,1}
  at index [2]
while loading In[3], in expression starting on line 20

fatal error on 2: ERROR: MethodError: `convert` has no method matching 
convert(::Type{RemoteRef{T<:AbstractChannel}}, ::Base.RemoteDoMsg)
This may have arisen from a call to the constructor 
RemoteRef{T<:AbstractChannel}(...),
since type constructors fall back to convert methods.
Closest candidates are:
  call{T}(::Type{T}, ::Any)
  convert{T}(::Type{T}, !Matched::T)
  RemoteRef()
