cleanupFunc() (registered via Py_AtExit) called C++ `delete pymodule` on a PyObject* created by PyModule_Create. That PyObject is owned and ref-counted by Python and allocated with Python's own allocator, so freeing it with the system allocator aborted with 'free(): invalid pointer' on every `import OpenFrescoPy` at interpreter finalization. Python releases the module itself during shutdown; removing the bogus delete (matching OpenSees's cleanupFunc) makes import exit cleanly. Affects only the importable module path.

OpenFrescoPyand exiting the interpreter aborted withfree(): invalid pointerduring finalization. Fix inPythonInterpreter.cpp— details in the commit. Reproduced and verified on Linux (python3 -c "import OpenFrescoPy"), and the loadPackage integration tests exit cleanly with the fix.🤖 Generated with Claude Code
