Error during optimization since upgrade from 1.1.1 -> 1.1.2

Version: 1.1.2
Minimum reproducible example:

```python
from datetime import datetime
from prophet import Prophet

df = pd.DataFrame([
{"unique_id": 1, "ds": datetime(2022, 12, 1), "y":5.0},
{"unique_id": 1, "ds": datetime(2022, 11, 1), "y":2.0},
])

def_model = Prophet(
yearly_seasonality=False,
weekly_seasonality=False,
daily_seasonality=False,
interval_width=0.95,
seasonality_mode="multiplicative",
changepoint_prior_scale=0.05,
growth="linear",
)
def_model.add_seasonality(name="Yearly", period=365.25, fourier_order=2)

# Fit the model to the training data
def_model.fit(df)
```

Output:
```

RuntimeError: Error during optimization!

When I run the command from the log I get a `Segmentation fault` like this:
```bash
/home/username/.cache/pypoetry/virtualenvs/forecast--1ch3c7_-py3.9/lib/python3.9/site-packages/prophet/stan_model/prophet_model.bin random seed=61655 data file=/tmp/tmp6m8x14sl/t6aoslvh.json init=/tmp/tmp6m8x14sl/qmjcj183.json output file=/tmp/tmp6m8x14sl/prophet_model_x1hgw42/prophet_model-20230126120014.csv method=optimize algorithm=newton iter=10000
```

This makes me think `prophet_model.bin` is somehow corrupted.
