[petsc-dev] array bounds exceeded?

[Adrian Croucher]

I just pulled the latest 'next' branch and compiled. I noticed the 
following warning- can this be ignored or is it possibly trouble?

           CC linux-gnu-c-opt/obj/src/dm/impls/plex/plexgeometry.o
/home/acro018/software/PETSc/code/src/dm/impls/plex/plexgeometry.c: In 
function ‘DMPlexComputeGridHash_Internal’:
/home/acro018/software/PETSc/code/src/dm/impls/plex/plexgeometry.c:493:90: 
warning: array subscript is above array bounds [-Warray-bounds]
              for (d = 0; d < dim; ++d) {segA[d] = 
PetscRealPart(ccoords[edge*dim+d]); segA[dim+d] = 
PetscRealPart(ccoords[((edge+1)%(dim+1))*dim+d]);}
