> Assertion failed: (bp != NULL), function PyObject_Malloc, file > Objects/obmalloc.c, line 755. This one gives one probable cause of the problem: - in Modules/_multiprocessing/connection.h, connection_send_obj() releases the GIL around a call to conn_send_string(). - in Modules/_multiprocessing/socket_connection.c, conn_send_string() uses PyMem_Malloc() This is wrong (the GIL must be held when using the PyMem_* and PyObject_* functions), and is probably the cause of the failed assertion.

This one gives one probable cause of the problem:

- in Modules/_multiprocessing/connection.h, connection_send_obj()
releases the GIL around a call to conn_send_string().
- in Modules/_multiprocessing/socket_connection.c, conn_send_string()
uses PyMem_Malloc()

This is wrong (the GIL must be held when using the PyMem_* and
PyObject_* functions), and is probably the cause of the failed assertion.
