I've been using prophet in R on windows for several months now and have recently started seeing random RStudio crashes. Prior to a few days ago, I was having no issues. I know that's not much to go off of, but I'm hoping someone can recognize what might be going on with my system. I've noticed that it crashes more frequently when n.changepoints is higher than the default of 25.
I see the crashes on both R 3.4 and 3.5. I have Rtools installed properly and can compile cpp code inline as documented in the Rstan installation.
Here is in the system that I'm working on. I have the latest version of prophet and Rcpp.

Here is the code that I'm running. It sometimes (1/5 times?) crashes Rstudio with a "session terminated" error.
for (i in 1:length(f_names)) {
d <- data_list[[i]]
m <- prophet(df = d,
holidays = h_daily,
n.changepoints = 100,
changepoint.prior.scale = 100)
future <- make_future_dataframe(m, periods = 14, freq = "day")
f <- predict(m, future)
forecast_list[[i]] <- f
}
If you've ever encountered something like this or know what I can do to give more info, please advise!
Edit: I'm using Rstudio 1.1.447. This also happens in Rgui and R command line.
