Upgrading to CRA 5.0: Allocation failed - JavaScript heap out of memory

[fgatti675]

Hi everyone,

I am the developer of a React-based CMS, used as a dependency in conjunction with React.

Everything was working fine, until the release of react-scripts: 5.0.0.
Just upgrading that dependency makes the build take a long time and crash with a
Allocation failed - JavaScript heap out of memory error.

The only way to make my project run right now is downgrading to version 4.0.3.

I have tried changing the max-old-space-size to 10gb, but it just takes longer to throw the same error. It seems like something is leaking memory.

This thing is driving me completely crazy and any help on how to solve it would be highly appreciated!

A link to our repository in case it helps checking the dependencies:

Did you try recovering your dependencies?

I have tried every possible combination regarding dependencies, both of the library and of the client projects.
I have also checked every dependency issue tracker to see if any were having an out of memory issue and I found none.

Environment

Environment Info:

  npmGlobalPackages:
    create-react-app: Not Found

Steps to reproduce

Simply following the steps in our quick-start:
https://firecms.co/docs/quickstart
(You don't need a Firebase project to reproduce the bug).

Since CRA now uses version 5.0.0 of react-scripts by default, our library is broken by default :(

Thanks in advance for any help!
