  tcsh: fix abort in cleanup_until(), caused by internal xgetpass()
  
  The xgetpass() function pushes a cleanup entry for &osa, but then
  attempts to flush the stack until an entry matching &sa.  The two
  object pointers do not match, so the stack is popped too much,
  and then cleanup_until calls abort() when it unexpectedly hits
  the bottom of the cleanup stack.
