I had weird results running this model on windows. At first it worked fine, then without changing anything it crashed RStudio a few times in a row. Now it’s back to working fine. Also, when it caused R to crash it looked like the model was able to run and return the print statement.
Here’s the code and options I was using
library(rstan)
options(mc.cores = parallel::detectCores(FALSE))
rstan_options(auto_write = TRUE)
stan("model.stan", chains = 1, iter=1, warmup=0, algorithm = "Fixed_param")
And here’s my sessionInfo()

I also want to mention that I’ve had problems with the ODE solvers crashing Rstudio on windows as well. I brought it up in this thread. When i encountered those problems it was very inconsistent. At one point I had a RK45 solver working fine; then, when I added one more parameter to the ODE system the model would compile but crash RStudio during sampling. I also couldn’t get the BDF solver to work at all. Not sure if any of this is related to the algebra solver.
