Subject: [Bug libfortran/19155] New: blanks not treated as zeros in 'E' format read
X-Bugzilla-Reason: CC

List-Id: <gcc-bugs.sourceware.org>

This is the NIST 110 failure, reduced.

$ cat blanks.f
      program blanks
      a = 42.
      open(19)
      write(19,'(A15)') 'E+00'
      rewind(19)
      read(19,'(E15.8)') a
      print *,a
      end
$ gfortran blanks.f
$ ./a.out
At line 6 of file blanks.f
Fortran runtime error: Bad value during floating point read
$ gfortran -v
Using built-in specs.
Configured with: ../gcc/configure --prefix=/home/ig25 --enable-languages=c,c++,f95
Thread model: posix
gcc version 4.0.0 20041224 (experimental)

This is a regression from g77:
$ g77 blanks.f
$ ./a.out
  0.
