I don't know why the "list" part does not work.  Maybe it is a bug, it
is hard to say without more information.

I believe the discrepancy between "break" and "print" is because "break"
puts a breakpoint on the first source line of the function -- which
occurs after the function prologue.  If you really want a breakpoint at
the entry point, you can use "break *function".  Usually you want the
default behavior here, though.
