FWIW that is a configure flag, not a flag to the compiler, so I see no problem with this. The default build has not changed, it just exposes another way to build the interpreter. We've done this in the past with things like --enable-optimizations and such flags.
In this case it appears to enable "new" code... though from the looks of the issues around this one, perhaps that is really old code just being readded and made available via a flag? That isn't clear to me at a quick glance on the issues. Just that it used to use TLS, was changed to ContextVar, and this flag allows it to keep using TLS. -gps On Sun, Mar 1, 2020 at 2:41 AM Antoine Pitrou <anto...@python.org> wrote: > > I don't know.
