[petsc-users] 64 bit integers

I want to build my application with 64 bit integer support
because of the size of the problem I am working on.
I compiled petsc with the option /--with-64-bit-indices=1/.
In my Fortran code some petsc vectors are initialize by taking
values from Fortran arrays.
I used PetscInt indexes to reference both petsc and fortran vectors.
It used to work with 32 bit indexes.
Will it still be the case for the 64 bit case?

Thank you
