I'm using Python 3.5.2 to be precise. I have code that is roughly equivalent to: import sys import traceback def handle_exception(exc_type, exc_value, exc_traceback): traceback.TracebackException(exc_type, exc_value, exc_traceback, capture_locals=True) sys.excepthook = handle_exception For one of the clients the following error happened: Traceback (most recent call last): File "...", line 222, in ... File "...", line 160, in ... File "...", line 878, in ...

Could you please provide a script that reproduces an issue? Seems the repr of uninitialized CDLL instance is used. It causes an infinite recursion in attempt to resolve not set private attributes (_name, _handle, _FuncPtr).

I was not able to reproduce it. The origin "unhandeled" exception happens after ctypes.cdll.LoadLibrary fails to load a library: Traceback (most recent call last): File "...", line 852, in ... File ":/ctypes/__init__.py", line 425, in LoadLibrary File ":/ctypes/__init__.py", line 347, in __init__ OSError: [WinError 126] 找不到指定的模組 Then we raise our own exception.

Proposed patch fixes an infinite recursion in a repr of uninitialized CDLL instance.
