Segmentation fault

If user inputs a file that can't be parsed, the whole thing fails, and the entire program fails without ability to try/catch the error. Is there a way around this or would it be possible to modify this to do that. Thanks!

No source file, test, or parser entry point is named in the issue. Reproduce the crash with a file that cannot be parsed, then trace the input path through the C++ parser and Python-facing entry point. Done means malformed input produces a catchable error instead of terminating the program, with a regression test covering the case.
