I can replicate the problem on:
 
IDL> help,/str,!version
** Structure !VERSION, 7 tags, length=44:
   ARCH            STRING    'x86'
   OS              STRING    'linux'
   OS_FAMILY       STRING    'unix'
   RELEASE         STRING    '5.4'
   BUILD_DATE      STRING    'Sep 25 2000'
   MEMORY_BITS     INT             32
   FILE_OFFSET_BITS
                   INT       =       32
