Confirmed on i386-linux.

Same thing happens without -fdefault-integer-8 on:
      character(len=6_8) hed, final
      data final /'foo'/
      data hed /'bar'/
      if (hed == final) call abort
      end

This happens with all character functions (like gfortran_copy_string, see PR
21083): using an integer(8) variable for the length of a string does not work.
We need a global fix for that.

Well, this bug seems to have been fixed by Paul Thomas' character patches. I
don't see the segfault any more on i686-linux (neither this one nor the ones in
the duplicate bug, PR21083).

Could someone confirm this on another platform (say, ppc-darwin)?
