[Bug libfortran/25403] New: gfortran run-time error with multiple tabs in format continuation

[mast at colorado dot edu]

If a format statement is continued onto another line and the continuation
line is indented with more than one tab after the continuation character,
there is
a runtime error such as
Fortran runtime error: Unexpected element in format
(i4,i4,                                                             i4,i4)
                                                           ^
A test program for this is:
       do i=1,1
          do j=1,2
            do k=1,1
              do l=1,1
                write(*,101)i,j,k,l
101             format(i4,i4,
     &              i4,i4)
              enddo
            enddo
          enddo
        enddo
        call exit(0)
        end

Where the indentation is with tabs (e.g., tabify in emacs).

Fails on Fedora Core 4, gcc-gfortran-4.0.2-8.fc4
Also fails under Mac OS X , gcc version 4.1.0 20051026 (experimental)
