I have a very simple test model with a truncated likelihood statement in it:

```
data{
int nbirds;
vector[nbirds] darrive;
array[nbirds] int clutch;
array[nbirds] int success;
}
parameters {
real logit_psuccess;
real log_avgclutch;
real log_b_date;
}
model {
success ~ binomial_logit(clutch, logit_psuccess);
logit_psuccess ~ normal(1, .2);
log_avgclutch ~ normal(1, .2);
log_b_date ~ normal(0, .2);
vector[nbirds] alpha = log_avgclutch + log_b_date * darrive;
clutch ~ poisson(exp(alpha)) T[1,];
}
```

On my Mac, with cmdstan 2.31.0 , this runs with no trouble.

On my Windows machine, with cmdstan 2.30.1, the compilation fails and I get:

```
Outcomes in truncated distributions must be univariate.
```

The versions are different, but is that really the cause of my problem here? And why does the version on windows think that the likelihood for `clutch`

is *multivariate* ?
