Subject: [PATCH] [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)
