STINNER Victor <vstin...@python.org> added the comment:
If I the comment the following assertion in PyEval_EvalCodeEx():
assert ((((PyCodeObject *)_co)->co_flags & (CO_NEWLOCALS | CO_OPTIMIZED)) == 0);
The garbage collector fails while visiting builtins of the function with
func_traverse(), at line:
Py_VISIT(f->func_builtins);
I guess that the problem is that f->func_builtins doesn't hold a strong
reference to builtins.
Error:
