[Bug fortran/17941] New: gfortran: parser chokes on complex literal constant

[anlauf at hep dot tu-darmstadt dot de]

Hi,

here's another problem, this time with "legacy f90" code:

program gfcbug17
  ! gfortran cannot parse this complex constant:
  complex, parameter :: c0 = (- 0.5, -0.5)
  print *, c0
end program gfcbug17

I get:


 In file gfcbug17.f90:3

  complex, parameter :: c0 = (- 0.5, -0.5)
                                  1
Error: Expected a right parenthesis in expression at (1)


Apparently the space between the "-" and 0.5 lets the parser choke.
Can the parsing rules be relaxed to accept the above form?

Cheers,
-ha
