Thank you, but I don't think this is a duplicate of issue42717. This crash is
probably caused by the parameter "target" of Thread. "Target" accept the
"callable object". Defaults to None. In this program, it's assigned to a "Int
object". I think a pre-checking of parameter for such error should be added.
Minimal test case should be:
===============================
import threading
for i in range(10):
t = threading.Thread(target=1, daemon=True).start()
=================================
In fact, I try this one. No loop, It sometime crashes the parser.(not always,
twice in ten times)
==================================
import threading
t = threading.Thread(target=1, daemon=True).start()
==================================
