[svn-r3131] Purpose:
Bug fix Description: Non-optimized conversions have a memory overwrite bug when the destination size of a compound datatype is greater than the source size. Solution: Corrected direction of walking through the destination array for final copying. Platforms tested: FreeBSD 4.2 (hawkwind) & Cray J90 (killeen)
