I see that the array arguments to dneupd are declared like this:
integer iparam(11), ipntr(14)
logical select(ncv)
Double precision
& dr(nev+1) , di(nev+1), resid(n) ,
& v(ldv,ncv) , z(ldz,*) , workd(3*n),
& workl(lworkl), workev(3*ncv)
so maybe enabling bounds checking for this code would provide some
pointers (with g77, it is -ffortran-bounds-check or -fbounds-check)?
