Description:   Last confirmed: 2004-07-08 07:06 Opened: 2004-07-08 07:05 
For the Ada testcase:

procedure P is

  type my_array is array (1..6) of Integer;
  A : my_array;

  function Q return my_array is
  begin
    return A;
  end;

begin
  A := Q;
end P;

I get with gcc -m64 on sparc-sun-solaris2.8:

The problem comes from the removing of OImode after GCC 3.2.x.
