Segmentation fault when trying to load large json file
I have a 1.1GB json file that I try to load with `pandas.json.load`:

```
import pandas as pd
with open('/tmp/file.json') as fileh:
    text = pd.json.load(fileh)
```

It breaks with the following output

```
Error in `python3': double free or corruption (out): 0x00007ffe082171f0 ***
```

I can load the file with Pythons built-in json module. What is going wrong here?
