This code is here. 

           if (filename .ne. PETSC_NULL_CHARACTER) then
              filename = trim(filename)
           endif

Maybe filename should not be used as the destination?

I am getting a segv when calling a Fortran subrouting from C, where PetscInit is called in the Fortran code only with a string for the rc file.

We have seen this on multiple platforms.

I got it in totalview and the segv was on the trim(filename) method
