rstanarm stan_jm crash - Error in check_stanfit(stanfit)

[etcl1]

Summary:

I was following the example in the rstanarm joint model vignette. I was at the very basic mod1 in the vignette and as I ran it, an error message pops out.

`SAMPLING FOR MODEL 'jm' NOW (CHAIN 1).

Chain 1: empty_nested() must be true before calling recover_memory() [1] "Error in sampler$call_sampler(args_list[[i]]) : "
[2] " empty_nested() must be true before calling recover_memory()"

error occurred during calling the sampler; sampling not done Error in check_stanfit(stanfit) : Invalid stanfit object produced please report bug`

I then ran mod1 again and the following pops out:

Error in sampler$call_sampler(c(args, dotlist)) : empty_nested() must be true before calling recover_memory()

So it looks like I'm requested to file a bug report. Any help would be very much appreciated.

The version of the rstanarm package I am running is 2.21.1

Hmm, haven't ever seen an error like this before! @jgabry @bgoodri Any idea where this might be coming from? I'm guessing it is rstan and the sampling is failing to start / initialise for some reason...?

Hmm, I think I've seen that before but it's been a while and I don't remember the reason for it. It's possible that upgrading to a more recent version of R (>= 4.0) will do the trick but @bgoodri might have a better suggestion.

It is quite tedious to get RStan-related things to work correctly on Macs with R 3.x .
