File with syntax error successfully parses with `--keep-comments`

[mn416]

Hi,

I've got the following file called parse_error.f90. It contains invalid Fortran code due to a missing then keyword in the if statement. Notice that the file begins with some white space (a single empty line is sufficient to see the issue).

  
  
  
module m
  integer :: x
contains
  subroutine foo()
    if (.true.)
      x = 0
    end if
  end subroutine
end module

Running psyclone parse_error.f90 correctly gives a parse error. Running psyclone --keep-comments parse_error.f90 prints nothing and simply returns: there is no parse error and no code emitted.

I'm on PScylone commit f2023c8 (1 May) and fparser commit 7d396b6 (latest).
