Thanks beforehand for your help!!

Start by reproducing stan(file="simple_poisson_regression.stan", data=stan_data) with RStan 2.17.3, R 3.4.0, and Windows 7, then inspect the compiler output referenced by compileCode and the generated .err.txt file. Done means identifying a reproducible cause and a documented fix or confirming that the available report is insufficient.
