Hello,

This is a crosspost from my [github issue](https://github.com/stan-dev/rstan/issues/1001).

Whenever I attempt to compile any stan file in Rstan, I get the following error and my Rsession is aborted.

```nohighlight
terminate called after throwing an instance of 'std::system_error'
  what(): Invalid argument
Abort trap: 6

```

To get this error, I put the following stan code in `example.stan`

```nohighlight
// The input data is a vector 'y' of length 'N'.
data {
  int<lower=0> N;
  vector[N] y;
}

// The parameters accepted by the model. Our model
// accepts two parameters 'mu' and 'sigma'.
parameters {
  real mu;
  real<lower=0> sigma;
}

// The model to be estimated. We model the output
// 'y' to be normally distributed with mean 'mu'
// and standard deviation 'sigma'.
model {
  y ~ normal(mu, sigma);
}

```

Then, I call

```nohighlight
rstan::stan_model(file = "example.stan")

```

Below is my sessionInfo:

```nohighlight

I’m not sure why this is happening because I know that `rstan` was working on my machine before.

Any help is appreciated!

Eric.
