<div dir="ltr">Harvey,<div><br></div><div>Molpro is using 8-byte integers, and the BLAS/LAPACK library you are linked against has 4-byte integers (or at least this is what Molpro's configure has deduced). One of the 8-byte integer values is simply too large to be represented using a 4-byte integer, and thus the program crashes.</div><div><br></div><div>The solution is to use a BLAS/LAPACK library with 8-byte integers. If you already are and configure just got it wrong then you can manually hack the values of BLAS_INT and LAPACK_INT which are defined in the MACROS variable in CONFIG file.
