StackOverflowError when sampling from mixture model

[BenjaminJCox]

MWE:

using Distributions
using DistributionsAD
using Random

test_mm = MixtureModel([TuringDenseMvNormal(randn(10), collect(I(10))) for comp in 1:10])
rand(test_mm)

This type of code comes up as I construct a mixture distribution inside of the function I take the gradient of, so the construction of the mixture must explicitly be these distributions (otherwise one gets covert errors).

I have no idea why this behaviour happens, but it occurs even when only 1 component is in the mixture.
For now I can get around it by sampling the vector of distributions then sampling the result, but this is not ideal.
