You can't "catch" it. It's not a mere Exception, it's a fatal error that effectively crashes the interpreter itself. At best, you could perhaps use the `multiprocessing` or `subprocess` modules to segregate the part of your program that uses ctypes and then try and recover when you detect that the subprocess has crashed. Instead, if possible, fix the C program and/or ensure that there's not an error in your ctypes interfacing code.
