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 WARNING[L1,P0] (CarpetLib): Error in prolongate_3d_rf2::coeffs_3d_rf2 RT=CCTK_REAL4 ORDER=11 n=10 y0=0, res=-0.000732422 }}}
