<p><span lang="EN-US" style="font-family:"Calibri","sans-serif"">The attached patch fixes the bug you reported below; it simply replaces scalar variables as actual arguments in calls to various print routines in ARPACK with (/ scalar /) to turn them into a
rank 1 array with a single entry. The dummy arguments are defined as datatype(*) so the error reported by gcc is correct.<o:p></o:p></span></p>
