Marc, I modified ___cleanup as follows: ------------------------------------------------------- ___EXP_FUNC(void,___cleanup) ___PVOID { /* * Only do cleanup once after successful setup. */ if (setup_state != 1) return; setup_state = 2; //___cleanup_mem (); //___cleanup_os (); } ------------------------------------------------------- This seems a bit odd... I do this in ipython: Process Python finished Python 2.7.1 (r271:86832, Dec 29 2010, 01:38:09) Type "copyright", "credits" or "license" for more information.

I had already tried commenting out ___cleanup_mem and ___cleanup_os. Only having ___cleanup_mem causes Python to exit also.  I was just going to look at this a bit more.  I'll try to comment out ___cleanup_mem first and see which of the lines in ___cleanup_os is causing the trouble.

Niether of these worked for Python.  However, the first one did cause "Cleanup successful\n" to be printed to the screen when calling client in gambit/tests.

Good to know.

For the Python problem could you comment out each line of ___cleanup_os in turn to see which call causes the problem :

void ___cleanup_os ___PVOID {  ___cleanup_io_module ();  ___cleanup_tty_module ();  ___cleanup_dyn_module ();  ___cleanup_files_module ();  ___cleanup_shell_module ();  ___cleanup_time_module ();  ___cleanup_base_module (); }

___cleanup_os is at the end of lib/os.c .
