Sooo, more Optim getting ready for v0.6 material. I fixed the macro problems in Optim fails on v0.6 - #6 by pkofod but the tests still do not pass, as I get the following error
ERROR: LoadError: LoadError: BoundsError: attempt to access 2×2 Array{Float64,2} at index [3]
in macro expansion at /home/pkm/.julia/v0.6/Optim/src/cg.jl:200 [inlined]

from the lines
@simd for i in 1:state.n
@inbounds state.y[i] = state.g[i] - state.g_previous[i]
end
I tried adding shows in there, and indeed, when I try to index into the third element of any of the three (y, g, g_previous) 2x2 matrices, it says I’m out of bounds. However, the following examples runs fine
type State
y
g
g_previous
n
end
the_state = State(rand(2,2), rand(2,2), rand(2,2), 4)
function update!(state)
@simd for i in 1:state.n
@inbounds state.y[i] = state.g[i] - state.g_previous[i]
end
end
update!(the_state)
If I print the types, they are all 2x2 Matrix{Float64,2}'s.
I’m not expecting anyone to go through the code to understand what’s going on, I’m just looking for any good ideas for how to debug this. Thanks
