Thanks, I think that's fixed that problem, but it looks like there might 
be another one now. When I build my code I'm getting an error when I 
call SNESSetJacobian():

1565 |          SNES_Jacobian, self%context, ierr)
       |                                           1
Error: There is no specific subroutine for the generic ‘snessetjacobian’ 
at (1)

The self%context object I'm passing in for the ctx argument is a derived 
type, which used to work ok.
