Description
RStanARM Version:
2.21.2
R Version/Operating System:
R version 4.0.5 Ubuntu 20.04
I installed rstarnarm with:
install.packages("rstanarm", repos = c("https://mc-stan.org/r-packages/", getOption("repos")))
Running the following code causes both R an RStudio to crash. No error messages are reported. I have fresh installation of both R, rstan and rstanarm.
library(rstanarm)
library(simsurv)
covs <- data.frame(id = 1:200,
trt = stats::rbinom(200, 1L, 0.5))
d1 <- simsurv(lambdas = 0.1,
gammas = 1.5,
betas = c(trt = -0.5),
x = covs,
maxt = 5)
d1 <- merge(d1, covs)
f1 <- Surv(eventtime, status) ~ trt
m1a <- stan_surv(f1, d1, basehaz = "ms", chains=1,refresh=0,iter=600)

Research direction
Start by running the provided simsurv and stan_surv example on the stated R and Ubuntu versions, then trace the stan_surv entry point to identify where the process crashes. Done means the example no longer crashes and a regression check covers this case.
