Yes, but for an unrelated reason, that's why I filed that as a different bug.

Well, the problem now is not just "requiring a lot of memory" in a generic sense
but more like requiring a lot of memory *per* CPU.
In fact, I can build the package on machines with 16 GB of RAM having
1 CPU but not on machines with 16 GB having 2 CPUs, where I get this:
c++: fatal error: Killed signal terminated program cc1plus
compilation terminated.
Could you please adjust the number of CPUs to be used according
to available memory?
I did something like that in graph-tool for the same reason:
https://salsa.debian.org/python-team/packages/graph-tool/-/commit/315bc676236d997573ccdda8d820376755744dab
but I believe now there are more advanced ways to achieve the same.
(Sorry for my flaky memory, Cc: Helmut who will probably remember it)
Thanks.
