Segfault when using python_autoreload

[sobolevn]

For some reason I have now started to receive segmentation fault errors in development. It does not happen all the time. Just happens at some unpredictable cases.

I have found two solutions (hacks):

1. Add --noreload option to runserver command
2. Add import threading; threading.stack_size(2*1024*1024) # noqa to the top level of manage.py

Does it make any difference if you add ENV JSON_MAX_STACK_BUFFER_SIZE=1024 before running pip?

@ncopa I will test this setting shortly, thanks.

@ncopa nope, it did not work.

But import threading; threading.stack_size(2*1024*1024) works.

So, I have tried to increase JSON_MAX_STACK_BUFFER_SIZE's value to 2048. And it still fails.

I guess it happens, because JSON_MAX_STACK_BUFFER_SIZE setting is specific to ujson, while I having trouble with django_rest_framework.
