Node crashes when using toJson

[boatcoder]

I've tried it with v10.18.1, v10.19.0 and 12.16.1 and all of them fail the same way. Not sure what is going on here. This only started once I used toJson, and quits when I don't use it.

enzyme-to-json version: v3.4.4

[boatcoder]

Also tried it on linux (in a docker) and it crashed the same way

I'm using this on node 12 without any issue...

Any ideas @adriantoine ?

[adriantoine]

Hi,

It doesn't seem to be related to this library, did you have any issues using any other node libraries? Did you try to run your tests without enzyme-to-json? Also can you provide the complete test case to reproduce the issue?

Thanks!

[boatcoder]

The only change I need to make to the project is to add enzyme-to-json. Removing it removes the crash. I'm using storybook as well which has it's own snapshot serializer that does not cause the problem. I'll try to make some kind of minimal case after friday this week. Got a deadline to get done

I'm getting a very similar issue when mounting a component for snapshot testing. Tried enzyme 3.4.4 and 3.5.0 with Jest 24, 25, and 26. Tried it with using the helper toJson and with jest's snapshotSerializer config. Also tried with Node lts/dubnium and Node lts/erbium Was also able to reproduce the issue with the same config on a different machine and OS.
