Please see the SO post: https://stackoverflow.com/questions/66713071/ctypes-heap-pointer-is-damaged-between-c-and-python-linux-x86-64 In summary, when I return a pointer to a heap-allocated memory location from a C function, its most significant 32 bits are chopped off for some reason. I observed this behavior in Python 3.7 and Python 3.8, on Ubuntu 18.04 and Centos 7 (x86_64). |

Are you using a 64-bit version of python? What is sys.maxsize? |

Alright, I solved the problem. It was simply a typo: "restypes" instead of "res_types". It didn't cause a problem in Python 3.6 but obviously, something was changed. A nice error message might be nice when setting these attributes. |
