New issue 2868: Segfault with `*args` type annotation in inner function https://bitbucket.org/pypy/pypy/issues/2868/segfault-with-args-type-annotation-in
Ben Darnell: Running the following code in pypy3 (6.0.0 on mac, similar crashes have been seen on older versions of pypy3 running on linux) will segfault: ``` def f1(): def f2(*args: int): pass f1() ``` ``` $ pypy3 --version Python 3.5.3 (fdd60ed87e941677e8ea11acf9f1819466521bf2, Jul 30 2018, 08:59:51) [PyPy 6.0.0 with GCC 4.2.1 Compatible Apple LLVM 9.1.0 (clang-902.0.39.2)] $ pypy3 -X faulthandler /tmp/test.py Fatal Python error: Segmentation fault Stack (most recent call first, approximate line numbers): File "/tmp/test.py", line 1 in f1 File "/tmp/test.py", line 1 in <module> File "<builtin>/app_main.py", line 541 in exec_ File "<builtin>/app_main.py", line 769 in execfile File "<builtin>/app_main.py", line 84 in run_toplevel File "<builtin>/app_main.py", line 545 in run_command_line File "<builtin>/app_main.py", line 840 in entry_point Segmentation fault: 11 ``` This example was reduced from a source file defining a decorator. The bug appears to require a type annotation on a `*args` or `**kwargs` parameter (not an ordinary parameter) in a function defined within the local scope of another function (top level functions and class methods are not affected). _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
