"E8.0" is an illegal format descriptor, but g77 produces a wrong output
"0.1+01" for a value of 1e5, instead of a more sensible "********" .

$ cat tmp.f
      a = 1.e5
      write(*,'(E8.0)') a
      end
$ g77 --version
GNU Fortran (GCC) 3.4.6 (Debian 3.4.6-6)
[. . .]
$ g77 tmp.f
$ ./a.out
  0.1+01
$

OK, since the format descriptor is illegal, g77 has the right to produce
anything it likes, but producing a wrong output without warning is a poor
handling of the error.

Regards,
Ryo
