It can be reproduced when run test.test_socket.J1939Test (omitted in regrtests now, see issue45187) with Address Sanitizer. See for example https://github.com/python/cpython/pull/28317/checks?check_run_id=3625390397. It can be reproduced when run test.test_socket.J1939Test with unittest: $ ./python -m unittest -v test.test_socket -k J1939Test See J1939Test.log for output. The cause is using PyArg_ParseTuple() with format unit "k" (unsigned long) and variable of type uint32_t. PyArg_ParseTuple() should only be used with native integer types (short, int, long, long long), it does not support support types of fixed size (uint16_t, uint32_t, uint64_t). |
