Comment(by jdemeyer):

 I suspect this is behind it, start Singular and press `CTRL-C`:
 {{{
 $ sage -singular
                      SINGULAR                             /  Development
  A Computer Algebra System for Polynomial Computations   /   version 3-1-1
                                                        0<

 FB Mathematik der Universitaet, D-67653 Kaiserslautern    \
 > ^C// ** Interrupt at cmd:`$INVALID$` in line:''
 abort command(a), continue(c) or quit Singular(q) ?
 }}}
 So we get a stupid prompt instead.
