This is a known issue with nodejs and high memory usage, which happen
to be better with nodejs 12 (but only because gitlab assets compilation does
not go way above 2GB usage).

There is no way to fix it in general: you will always find use cases that
make
nodejs crash as soon as it is using GB of heap memory space.

Any nodejs < 14 version is affected (because who knows, v8 might make it
possible for node to fix it in nodejs 14) but not in the same way (some
fail at 1.4GB,
others at 2GB of heap space usage).

You can try running it with this flag:
webpack --max-old-space-size=4096

Note also that using a high value by default is not a good solution either.
