For SIGKILL, my gdb reports "Program terminated with signal SIGKILL, Killed." and there is no stack 
trace. Is this what you see?

If your program stops "normally", not from receiving some signal, set breakpoints on "exit" and 
"_exit".

The normal stop sequence is to call exit(), which runs all the atexit() functions (the midas atexit() 
function prints the message about "cm_disconnect_experiment not called at end of program") and 
calls _exit() to stop the program.

So if you see the midas message "cm_disconnect_experiment not called at end of program", it is a 
good indication that somebody (not mfe.c) called exit() on you. A breakpoint on "exit" should catch 
who does it.

Good luck,
K.O.
