I cannot reproduce this on 'next':

next $:/PETSc3/petsc/petsc-dev/src/snes/examples/tutorials$ ./ex19
-options_table -snes_monitor
PETSC_OPTIONS="-cublas 0" ./ex19 -options_table -snes_monitor
lid velocity = 0.0625, prandtl # = 1, grashof # = 1
  0 SNES Function norm 2.391552133017e-01
  1 SNES Function norm 6.839858507066e-05
  2 SNES Function norm 8.558777232425e-11
Number of SNES iterations = 2
#PETSc Option Table entries:
-options_table
-snes_monitor
#End of PETSc Option Table entries

Can you reproduce this with a PETSc example?

  Thanks,

     Matt
