I have tried to reproduce your problem by adding those two
lines to the Config and flash.par files, repectively, of
a standard Sedov setup.  I did not encounter your problem.

Please provide more information about your setup.
What gravity implementation are you using?
In particular, the units included and any modified Config
files would be useful.

Can you provide the output of the following command in
you object directory?

  ls -l Grid_apply*.F90 Grid_BC*.F90 gr_apply*.F90 gr_bc*.F90 Gravity*.F90



A caveat regarding the provided hydrostatic boundary conditions:
these are ported from the default implementation in FLASH2.
However, various setups in FLASH2 used their own implementations
overriding the defaults. You should also check whether the
algorithm used is appropriate for you or whether you should
provide your own.
