The files are not identical. fileA.dat terminates lines
with a line with a LF.  fileB.dat terminates lines with
a CRLF.

With gfortran 5.4.1 I can read fileA.dat.  Reading fileB.dat
generates

  At line 14 of file minimum_example.f (unit = 31, file = 'fileB.dat')
  Fortran runtime error: Cannot match namelist object name 30.00

With gfortran 6.1.1, I get the same results as with 5.4.1, except
the built executable aborts with a backtrace.

With gfortran 7.0.0, both files can be read.  So, the bug is
fixed on trunk.  You can update to trunk or ensure your files
have the format of fileA.dat.
