Hi Victor, Thanks for the answer!

Right? -Wdefault means -Wonce or -Walways? If the former, I don't expect many warnings to be emitted. > For example, on test_os, PYTHONMALLOC=debug increases the peak memory > usage from 10.5 MiB to 15.8 MiB: +50%. I see. For my use cases, this would be acceptable :-) But I think this should be documented, for example: """Currently, developer mode adds negligible CPU time overhead, but can increase memory consumption significantly if many small objects are allocated. This is subject to change in the future."""
