Comment (by dave):

 It's probably a bug that you're able to crash Python, but the two examples
 you are reporting as bugs don't mean what you think they do:

 {{{#!cpp
         bp::def("bug1", &f, ("x", "y", bp::arg("z")));
         bp::def("bug2", &f, ("x", "y", "z"));
 }}}

 In particular, because the comma operator associates from left-to-right,
 what you've written there is equivalent to:

 {{{#!cpp
         bp::def("bug1", &f, bp::arg("z"));
         bp::def("bug2", &f, "z");
 }}}
