STINNER Victor <[email protected]> added the comment:
Hum, test_runpy fails something with a segfault and/or a recursion
limit because of my hack to rerun regrtest.py to set PYTHONHASHSEED
environment variable. The fork should be defined if main() of
regrtest.py is called directly. Example:
diff --git a/Lib/test/regrtest.py b/Lib/test/regrtest.py
--- a/Lib/test/regrtest.py
+++ b/Lib/test/regrtest.py

As Antoine wrote on IRC, regrtest.py should be changed later.
