Unreachable reached when using Dict for kwargs

General Usage
1

I am getting an unreachable reached crash, when I convert a result from NLsolve.jl back to my custum type after calling nlsolve with a Dict containing the keyword arguments. If I give the same keyword arguments to nlsolve explicitly, everything works as expected. Below is a MWE and the message that I get when Julia crashes. I am on Julia 1.6.1 and NLsolve 4.5.1. Am I doing something wrong here or should this not be happening?

using Tensors
using NLsolve

mutable struct Residuals{T}
    σ::SymmetricTensor{2,3,T,6}
    κ::T
    α::SymmetricTensor{2,3,T,6}
    μ::T
end

function frommandel!(r::Residuals{T}, v::Vector{T}) where T
    M=6
    r.σ = frommandel(SymmetricTensor{2,3}, view(v, 1:M))
    r.κ = v[M+1]
    r.α = frommandel(SymmetricTensor{2,3}, view(v, M+2:2M+1))
    r.μ = v[2M+2]
    return r
end

function foo_nocrash(cache)
    x = Residuals(ones(SymmetricTensor{2,3}), 1.0, ones(SymmetricTensor{2,3}), 1.0)
    res = nlsolve(cache, ones(14); method=:newton)
    frommandel!(x, res.zero)
end

function foo_crash(cache, options)
    x = Residuals(ones(SymmetricTensor{2,3}), 1.0, ones(SymmetricTensor{2,3}), 1.0)
    res = nlsolve(cache, ones(14); options...)
    frommandel!(x, res.zero)
end

A = rand(14, 14)
function f!(b, x)
    b[:] = A*x
end
cache = NLsolve.OnceDifferentiable(f!, rand(14), rand(14); autodiff=:forward)
options = Dict{Symbol, Any}(:method=>:newton)

# no problem if kwargs are given explicitely
foo_nocrash(cache)

# kwargs in Dict and call from function crashes
foo_crash(cache, options)

Reduced even more, in particular not using Tensors

using NLsolve

mutable struct Residuals{T} end

function noop(r::Residuals{T}, v::Vector{T}) where T
    return
end

function foo_crash(cache)
    res = nlsolve(cache, ones(14); (Dict{Symbol, Any}(:method=>:newton))...)
    x = Residuals{Float64}()
    noop(x, res.zero) # This call triggers it
end

A = rand(14, 14)
function f!(b, x)
    b[:] = A*x
end
cache = NLsolve.OnceDifferentiable(f!, rand(14), rand(14); autodiff=:forward)

foo_crash(cache)
  1. Crash does not happen if I change noop(x, res.zero) to noop(x, copy(res.zero)).
  2. Crash does not happen if I remove the type parameter on Residuals.

It shouldn’t, can you open an issue?
