Any clues from this?

@Charles_Driver, thanks for posting. Can you also post your Stan program? It’s not enough just seeing the compiler error.

I’ve seen stuff like this and I’ve been meaning to invest time in creating minimal examples to file a bug report. Hopefully your Stan program will trigger my memory or it’ll show a different issue that should be fixed.

The program is rather complex, but a MWE using rstan was easy to construct. replacing the two calls to data in the ode with numeric values like 1.0 avoids the compile error. I submitted an issue to github here: [https://github.com/stan-dev/stan/issues/2605](https://github.com/stan-dev/stan/issues/2605)

```
sm<-c('
functions{
  real[] ode(real time, real[] state, real[] theta, real[] xr, int[] xi){
    return state;
  }
}
data{
  int ndatapoints;
  real dT[ndatapoints]; // time intervals
  real dTsmall[ndatapoints];
}
model{
  vector[2] state;
  real theta[1];
  state=to_vector(integrate_ode_rk45(ode, to_array_1d(state), 0.0, rep_array(dTsmall[1],1 ), 
    theta, rep_array(dT[1],1), rep_array(1,1))[1,]); 
}
')

library(rstan)

stan_model(model_code = sm)
```
