[Bug] GHDL reports incomplete sensitivity list when rising_edge is enclosed in parenthesis

[pidgeon777]

This code returns a warning:

PROCESS_p: process(CLK)
begin
  if (rising_edge(CLK)) then
	sig <= INPUT_P;
  end if;
end process;

Warning message:

incomplete sensitivity list, signal "INPUT_P" is missing

but if I remove the parenthesis enclosing rising_edge, the warning disappears.
