It would help if the example were complete.  Not knowing what that would
be, I just tried with the necessary variables, to see what it would do.
I linked it with a copy of ncurses that I'd configured with
the trace option, and did

        NCURSES_TRACE=0x224 ./foo

to see.  For my example, the post_form() fails (E_NO_ROOM is -6):

called {new_form(0xbfa8a7bc)
+ called {Connect_Fields(0x805b540,0xbfa8a7bc)
+ return }0
+ called {form_driver(0x805b540,-291056)
+ return }0
return }0x805b540
called {post_form(0x805b540)
return }-6
called {set_current_field(0x805b540,0x804a1c8)
return }0

Making the screen bigger got a form to show up.  That may not be your
particular problem, but the trace feature can be helpful.
