Segmentation fault when trying to load large json file
#### Code Sample

```python
import pandas as pd
site_filename = "/path/to/file.json"
df = pd.read_json(site_filename, lines=True)
```

Output: `Segmentation fault`

#### Problem description

Similar issue to [#11344](https://github.com/pandas-dev/pandas/issues/11344), with a 1.2G file (specifically 1216272 bytes) with 70+ keys across the JSON records and multiple nested keys.

GDB output:

Bizarrely, the seg fault doesn't occur in the `ipython` REPL e.g. executing the script with `%load produce_site_report.py` is just fine.

#### Expected Output

No `Segmentation fault`.

#### Output of ``pd.show_versions()``
