Crash when the target json file is too large

[Butter934]

My code is here:

# driver.py
import numpy as np
from pyannotate_runtime import collect_types

if __name__ == '__main__':
    collect_types.init_types_collection()
    collect_types.start()
    np.core.test()
    collect_types.stop()
    print("test finished")
    collect_types.dump_stats('type_info.json')

and crashed after some time.

Is that because the target json file too large? What tricks can be used to run it correctly?
