I am trying to fit a model using stan_surv from the rstanarm package. The crash happens when I try to fit this model:
fit <- stan_surv(Surv(time, event) ~ 1, data = df, basehaz = 'exp')
The model (and any other stan_surv model that I have tried) immediate sends an error that says
====== C stack trace ==========
and the R crashes. R and all packages are up-to-date. System information:
R version 4.0.3 (2020-10-10)
Platform: x86_64-w64-mingw32/x64 (64-bit)
AMD Ryzen 9 9350X 16-core processor, 64 GB RAM
Running under: Windows 10 x64 (build 19041)
Interestingly, this crash occurs on my desktop PC (my supposed power computer for running Bayesian things) and did not occur on my MS SurfacePro laptop last night. Both are running what I believe to be the same versions of rstan and rstanarm.
I have no idea why this happening. Everything else in R seems to be working, including accessing stan via survHE. So I suspect this is an rstanarm problem. No idea how to check. Help appreciated.
