@vstinner, on Debian 9 I can see the problem as well but wasn't able to debug with the level of details you did. Could you please share the process you followed? What I found was: ./python -X dev test_lock_sigsegv.py Parent r_q: <Lock(owner=None)>, <Lock(owner=None)>, <BoundedSemaphore(value=2147483647, maxvalue=2147483647)> Fatal Python error: Segmentation fault Current thread 0x00007fab36124480 (most recent call first): File "/home/gus/Workspace/cpython/Lib/multiprocessing/synchronize.py", line 170 in __repr__ File "/home/gus/Workspace/cpython/test_lock_sigsegv.py", line 17 in child File "/home/gus/Workspace/cpython/Lib/multiprocessing/process.py", line 99 in run File "/home/gus/Workspace/cpython/Lib/multiprocessing/process.py", line 297 in _bootstrap File "/home/gus/Workspace/cpython/Lib/multiprocessing/spawn.py", line 130 in _main File "/home/gus/Workspace/cpython/Lib/multiprocessing/spawn.py", line 117 in spawn_main File "<string>", line 1 in <module> -11 Using GDB: (gdb) set follow-fork-mode child (gdb) run test_lock_sigsegv.py Starting program: /home/gus/Workspace/cpython/python test_lock_sigsegv.py [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
