Segmentation Fault on Bayesian Hidden Markov Model Tutorial

[trentfridey]

I am getting stuck running the HMM tutorial.
The problem is with running the sampler; everything up to then runs perfectly.

When I run the sampler code via the Julia REPL:

chn = sample(BayesHmm(y, 3), g, 1000);

I get a segmentation fault. This is running Julia 1.7.1 on Linux. My package environment is:

• Julia 1.7.1
• Turing v0.15.1
• StatsPlots v0.14.30

Is there something I should do to make the sampler run?
