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)
