New submission from Dave Odell: Here's a small program that crashes Python 3.
import winreg winreg.SetValueEx(winreg.HKEY_CURRENT_USER, 'Value', 0, 3, None) I get a 0xC0000374 exception (STATUS_HEAP_CORRUPTION) when trying to run this. Here's a stack dump: (snip) ntdll.dll!RtlpLogHeapFailure+0xa4 ntdll.dll! ?? ::FNODOBFM::`string'+0x10c7c kernel32.dll!HeapFree+0xa MSVCR100.dll!free+0x1c python34.dll!PySetValueEx+0xf8 python34.dll!PyCFunction_Call+0x12d python34.dll!call_function+0x2ab python34.dll!PyEval_EvalFrameEx+0x2259 python34.dll!PyEval_EvalCodeEx+0x65c python34.dll!PyEval_EvalCode+0x2e python34.dll!builtin_exec+0x1b5 python34.dll!PyCFunction_Call+0x12d python34.dll!call_function+0x2ab python34.dll!PyEval_EvalFrameEx+0x2259 python34.dll!PyEval_EvalCodeEx+0x65c python34.dll!function_call+0x15d python34.dll!PyObject_Call+0x61 python34.dll!ext_do_call+0x2ab python34.dll!PyEval_EvalFrameEx+0x22fe python34.dll!PyEval_EvalCodeEx+0x65c python34.dll!fast_function+0x14d python34.dll!call_function+0x311 python34.dll!PyEval_EvalFrameEx+0x2259 python34.dll!PyEval_EvalCodeEx+0x65c python34.dll!PyEval_EvalCode+0x2e python34.dll!run_mod+0x53 python34.dll!PyRun_StringFlags+0x9c python34.dll!PyRun_SimpleStringFlags+0x41 python34.dll!run_command+0x55 python34.dll!Py_Main+0x683 pythonw.exe!__tmainCRTStartup+0x166 kernel32.dll!BaseThreadInitThunk+0xd ntdll.dll!RtlUserThreadStart+0x1d System is Windows 7 64-bit, with stock x86-64 Python 3.4.0 binaries. Incidentally, I was feeding the 'None' to winreg.SetValueEx because that is the value that winreg.EnumValue returns for zero-length binary values. This is somewhat unexpected; I'd personally prefer to get b'' in that instance. ---------- components: Library (Lib), Windows messages: 215486 nosy: dmo2118, stutzbach priority: normal severity: normal status: open title: winreg.SetValueEx causes crash if value = None type: crash versions: Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21151> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
