the datetime type is defined as #define _PyTZINFO_HEAD \ PyObject_HEAD \ Py_hash_t hashcode; \ char hastzinfo; /* boolean flag */
typedef struct { _PyTZINFO_HEAD unsigned char data[_PyDateTime_DATE_DATASIZE]; } PyDateTime_Date; and data is used to calculate the hash of the object, not being 4 byte aligned, you get the bus error. Inserting three fill bytes, are making the data member 4-byte aligned solves the issue, however introducing an ABI change makes the new datetime ABI incompatible. For now I don't know a solution to make that change and keep the ABI compatible. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1620754 Title: hash(datetime.datetime(...)) fails with python3.5 on armhf (on an arm64 host) with a bus error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python-cryptography/+bug/1620754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
