It sounds like the new_panel() is the one which is failing.

 if ((wnd = newwin(lines, cols, begin_y, begin_x)) == NULL)
     return;

that "should" throw an exception, otherwise the caller has no
immediate way of know that the construction of the window failed.

   pan = new_panel(wnd);

try checking that for null. If it's segfaulting on panel access, it
would seem that the panel isn't there. Your show() routine explicitly
checks if panel is null, but the ctor doesn't. If you'll refactor a
bit you can call show() from the ctor to avoid code duplication in the
ctor.
