New submission from Natanael Copa <natanael.c...@docker.com>: Python assumes that the system default thread stack size is big enough for python, except for OSX and FreeBSD where stack size is explicitly set. With musl libc the system thread stack size is only 80k, which leads to hard crash before `sys.getrecursionlimit()` is hit.
See: https://github.com/python/cpython/blob/master/Python/thread_pthread.h#L22 Testcase: import threading import sys def f(n=0): try: print(n) f(n+1) except Exception: print("we hit recursion limit") sys.exit(0) t = threading.Thread(target=f) t.start() This can be pasted into: docker run --rm -it python:2.7-alpine docker run --rm -it python:3.6-alpine ---------- components: Interpreter Core messages: 308226 nosy: Natanael Copa priority: normal severity: normal status: open title: Bad assumption on thread stack size makes python crash with musl libc type: crash versions: Python 2.7, Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32307> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
