I monitored the VM's memory usage and it peaked at 1.6G. But after
testing, it seems 1024 also works.
I tested with 2048 (worked), 1024 (worked), and 512 (didn't work).

In that case... The attached patch would only increase the size when
generating a Docker container image. Would that be acceptable?

I think it'd be better to have it somehow dynamically increase, but I
don't see how I could determine the VM size needed for a given system
configuration. So perhaps the attached patch is an acceptable
compromise.
Kind regards,
