Comment (by barry.wardell):

 Replying to [comment:6 barry.wardell]:
 > This fix seems to have only been applied to the cell-centered version of
 the code. The original problem reported by Ian still exists. Can we apply
 the same fix to CarpetLib/src/prolongate_3d_rf2.cc (and possibly any other
 affected versions)?

 To answer my own question: no. The fix gets rid of the warning for 9th
 order, but a similar one appears for the 11th order operators:
 {{{
 WARNING[L1,P0] (CarpetLib): Error in prolongate_3d_rf2::coeffs_3d_rf2
    RT=CCTK_REAL4
    ORDER=11
    n=10
    y0=0, res=-0.000732422
