gfortran formatted read incorrectly reads beyond end of record when
record length is < io,format length.

Demo:
ian@ian:~/source/test> cat ftest.f95
program ftest
  integer i
  character*1 b(10)

  open (77, file='input_file')
  read (77, '(10A1)') b
  print *, b
end program ftest

ian@ian:~/source/test> cat input_file
Line 1
Line 2
Line 3
Line 4

ian@ian:~/source/test> gfortran -v
