New issue 2089: Crash in PyPy 2.6.0 (linux64) with gevent 1.1b1 https://bitbucket.org/pypy/pypy/issues/2089/crash-in-pypy-260-linux64-with-gevent-11b1
Jay Oster: Minimal test case to reproduce: https://gist.github.com/parasyte/b3e0f80b81a9c7b291d3 Requires gevent 1.1b1: ``` #!bash $ pip install --upgrade pip setuptools $ pip install gevent==1.1b1 ``` Occurs on pypy-2.6.0-linux64 (not on OSX). Earlier versions of PyPy are not affected. While building this minimal test case, I determined that the crash is dependent on stack depth, which the `depth` function exploits with recursion. `gevent.monkey.patch_builtins()` is new to 1.1b1, and patches `__import__` to operate atomically with a reentrant lock. This may be a gevent bug (I will file a ticket for their tracker as well.) I've seen two different stack traces from RPython with this test case, just keep running it until and you'll eventually see both. ``` Fatal error in cpyext, CPython compatibility layer, calling PyObject_GetItem Either report a bug or consider not using this particular extension <OperationError object at 0x7f482cd96940> RPython traceback: File "pypy_module_pypyjit_interp_jit.c", line 340, in portal_5 File "pypy_interpreter_pyopcode.c", line 3578, in handle_bytecode__AccessDirect_None File "pypy_interpreter_pyopcode.c", line 5853, in dispatch_bytecode__AccessDirect_None Segmentation fault (core dumped) ``` And this one less frequently: ``` Fatal error in cpyext, CPython compatibility layer, calling PyObject_GetItem Either report a bug or consider not using this particular extension <OperationError object at 0x7f4ff4e9df00> RPython traceback: File "pypy_module_cpyext_api_1.c", line 17394, in PyPyObject_GetItem File "pypy_module_cpyext_pyobject.c", line 850, in make_ref File "pypy_module_cpyext_pyobject.c", line 1854, in create_ref File "pypy_module_cpyext_pyobject.c", line 4587, in BaseCpyTypedescr_allocate File "pypy_module_cpyext_pyobject.c", line 850, in make_ref File "pypy_module_cpyext_pyobject.c", line 1738, in create_ref File "pypy_module_cpyext_typeobject.c", line 35294, in type_attach File "pypy_objspace_std_objspace.c", line 1038, in getattr File "pypy_interpreter_gateway.c", line 846, in BuiltinCode2_fastcall_2 File "pypy_interpreter_gateway.c", line 2779, in BuiltinCode_handle_exception Segmentation fault (core dumped) ``` _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
