The documentation of XtDisplayToApplicationContext() says "If the display
is not known to the Intrinsics, an error message is issued".  However,
XtDisplayToApplicationContext() drops core when it is invoked with a
display not known to Xt (at least when no other display is known to Xt,
i.e. when the internal display list is empty).

The culprit is the macro _XtGetPerDisplay in mit/lib/Xt/InitialI.h.
It doesn't check whether the display list is empty.
