Hi. Is it possible that the latest default branch does not translate a sandboxed pypy:? I do: python rpython/bin/rpython -O2 --sandbox pypy/goal/targetpypystandalone.py And get the traceback below after a bit of mandelbrot. Do we consider "default" the most stable branch? It is because I also have a fork (with the await-keyword), and I'd like to keep it up-to-date with the latest stable. Thanks!
