[Bug libfortran/19114] New: runtime error when reading complex*16 using formatted I/O
gfortran (snapshot as of 12/17/04) compiled code gives a runtime error when reading formatted complex*16 values using the following program: program testIO implicit none integer i complex*16 values(5) open(7,file='test1.dat',status='old') read ( 7, '(5E15.8)' ) ( values (i), i = 1, 5 ) print *, ( values (i), i = 1, 5 ) end The text file test1.dat contains: 2.E+00 0.E+00 2.52505826E-01 0.E+00 1.44380768E-04 -1.11464849E-18 1.01002561E-01 0.E+00-2.52507036E-02 0.E+00 The code was compiled and executed with gfortran bug.f; a.out, and produced the following error message: At line 8 of file bug2.f Fortran runtime error: End of file The code works correctly when compiled with g77 and ifort (Intel Fortran), and produces the output (g77): (2.,0.)
