Empty string at spanner bound causes infinite loop

The following snippet:

yields apparently infinite occurences of
programming error: Improbable offset for stencil: 1000001.000000 staff space
Setting to zero.
and I have to abort the program.
With 2.19.22, the same code gives
programming error: Improbable offset for stencil: -inf staff space
programming error: Improbable offset for stencil: -nan staff space
warning: Found infinity or nan in output. Substituting 0.0
and no sensible output.
