--- Comment #1 from Robert Potvliege <r.m.potvliege at durham dot ac.uk> ---
Reading a logical array through a namelist triggers an (apparently) spurious
run time error in some cases. E.g., when I am compiling the following code =
with
gfortran,

      program test
      logical, dimension(3,3) :: flc,flp
      namelist/inputdata/flc,flp
!
      read(5,inputdata)
!
      end program test

and read the following file,

&INPUTDATA
 FLC =3D T,
 FLP(1,2) =3D T,
/

the execution stops with the error message

At line 5 of file progtest.f90 (unit =3D 5, file =3D 'stdin')
Fortran runtime error: Bad repeat count in item 1 of list input

However, there is no error for the following input file

&INPUTDATA
 FLC =3D T,
 FLP =3D T,
/

or the following one

&INPUTDATA
 FLP(1,2) =3D T,
/

etc. No error is produced for any of these input files if I compile this sh=
ort
program with the Intel compiler I can access rather than gfortran.=
