[New-bugs-announce] [issue36963] PyDict_GetItem SegFaults on simple dictionary lookup when using Ctypes

[Apoorv Reddy]

New submission from Apoorv Reddy <apoorvreddy19 at gmail.com>:

I'm trying to use ctypes to speed up an internal function in my project. However, I'm getting a segmentation fault on a simple dictionary lookup in my C Code, on PyDict_GetItem(dict, key).

I have supplied a minimal version of the code I'm trying in C, which segfaults, with the Makefile and the Python driver code which loads the shared library.I have created a simple conda environment for Python 3.6 for the same.
