>Description:
This code:

      character*256 buff(0:10)
      character*80 strings(10)
      integer i,m1,m2

      i = 1
      m1 = 1
      m2 = 7
      buff(i) = 'tcase0a'
      strings(i) = buff(i)(m1:m2)
      write(*,*)buff(i)
      write(*,*)buff(i)(m1:m2)
      write(*,*)strings(i)

      stop
      end

should print "tcase0a" three times, the first time with 248
blanks attached.

However, with 'g77 [other options] -fbounds-check' it
doesn't.
