Narrowed down the trigger a bit more: const AbstractScalarOrVec{T} = Union{T,AbstractVector{T}} where {T<:AbstractFloat}
function mh1(
rng::Union{AbstractRNG,AbstractVector{<:AbstractRNG}},
Horiginal::AbstractScalarOrVec{<:T},
Hproposal::AbstractScalarOrVec{<:T},
) where {T<:AbstractFloat}
α = min.(1.0, exp.(Horiginal .- Hproposal))
accept = rand(rng) .< α
return accept, α
end
function mh2(
rng::Union{AbstractRNG,AbstractVector{<:AbstractRNG}},
Horiginal::AbstractScalarOrVec{<:T},
Hproposal::AbstractScalarOrVec{<:T},
) where {T<:AbstractFloat}
α = min(1.0, exp(Horiginal - Hproposal))
accept = rand(rng) < α
return accept, α
end
function mh3(
rng,
Horiginal,
Hproposal,
)
α = min.(1.0, exp.(Horiginal .- Hproposal))
accept = rand(rng) .< α
return accept, α
end
function g(spl)
h = spl.state.h
rng = Random.GLOBAL_RNG
θ = spl.state.z.θ
value, gradient = h.∂ℓπ∂θ(θ)
e1, e2 = value, value
# Doesn't work
is_accept, α = mh1(rng, e1, e2)
# Work
#is_accept, α = mh2(rng, e1, e2)
#is_accept, α = mh3(rng, e1, e2)
is_accept, α
end

What is the result on julia 1.3 (and if you can check, master). |
|
Seems to be fixed on 1.3 https://travis-ci.com/TuringLang/DynamicPPL.jl/jobs/271769735. |
|
Actually even 1.2. |
|
Okay so not sure what is left to do here, we are not making any more 1.1 releases. |
|
What about 1.0? |
|
But it seems to pass on 1.0 as well? |
|
No, it doesn't pass https://travis-ci.com/TuringLang/DynamicPPL.jl/jobs/271780848. |
|
Ah, I just looked at the build pass status. If the commit that fixed it can be found and backported then it could be included in a new 1.0.x release, yes. |
|
Restored backport-pending-1.0 label to #31405. This time, we'll just drop the new tests from the backport (#30954 (comment)). |
FYI, this is redundant. |
Cool, thanks! |
|
Fixed on master (actually on v1.2) |
Hi!
The following code triggers what looks like a compiler bug.
Here is the stacktrace:
and my
versioninfo():What seems to be a similar error also happens on other platforms (https://travis-ci.com/TuringLang/DynamicPPL.jl). The error doesn't affect the result of the function though, it just happens once when the function is compiled.
