Why these two ways of function definition lead to different optimization statuses?

I define the same objective function in two ways:

function logit1(α, X, y)
    loglike = -sum(y[i]*α'*X[i,:] .- log.(1 .+ exp.(α'*X[i,:])) for i=1:length(y))
    return loglike
end

function logit2(α, X, y)
    loglike = -sum(y.*(X*α) .- log.(1 .+ exp.(X*α)))
    return loglike
end

Then I run optimization using logit1 and logit2 respectively:

optimize(α -> logit(α, X, y), rand(size(X,2)), LBFGS(), Optim.Options(g_tol=1e-6, iterations=100_000, show_trace=true))

While both objectives lead to the same minimizer (as supposed to), the reported output are different. The first one gives “* Status: failure (objective increased between iterations)” but the second one gives " * Status: success".

Why does this happen?
