[Bug fortran/34771] New: Parenthesis around character variables: No expression

[Bug fortran/34771] New: Parenthesis around character variables: No expression

[burnus at gcc dot gnu dot org]

(c) and c
are regarded as the same for character variables; for other types (z) and z are
not the same.

gfc_get_parentheses (gfc_expr *e)
{
  gfc_expr *e2;

  /* This is a temporary fix, awaiting the patch for various
     other character problems.  The resolution and translation
     of substrings and concatenations are so kludged up that
     putting parentheses around them breaks everything.  */
  if (e->ts.type == BT_CHARACTER && e->ref)
    return e;

Test case:

subroutine a(c)
  character :: c(*)
  call b((c))
contains
  subroutine b(y)
    character :: y(*)
  end subroutine b
end subroutine

Due to the parenthesis, it should print:
"Error: The upper bound in the last dimension must appear in the reference to
the assumed size array"

(Error messages needs patch for PR 34665.)

This is, of course, fixed (GNU Fortran (GCC) version 4.4.0 20081109). What do
you want to do with 4.3??  If I remove the offedning part of
gfc_get_parentheses in 4.3.3 20081108 (prerelease), it bootstrap and regtests
OK.  Further, this bug is gone:-)

Paul

I think we have moved past this and close it.  4.3 is regressions only.
