Is this a regression?
Yes, the previous version in which this bug was not present was Angular 9 with CLI 9.
Description
Small project freshly migrated from ng9 to 10, I sometimes get a compiler crash with "JavaScript heap out of memory" during ng serve.
It never happened to me before ng 10.
Project is available here:
