Two minutes after posting this question I figured out the answer
myself. Just check "force far calls". Sorry about the waste of
bandwidth.

Re:Linking a Borland C OBJ-file with Delphi?

Does anyone have experience with linking an .OBJ file compiled
in Borland C++ 4.5 into a Delphi 1.0 program? Everything works fine
until the function returns from C to Delphi where it generates a GPF.

C-part: (objtest.c -> objtest.obj)
void pascal Hello()
{
}

Delphi-part:
procedure Hello; external;

{$L objtest.obj}

procedure TForm1.Button1Click(Sender: TObject);
begin
Hello;
end;

Error message:
Project TEST1.EXE raised exception class
EGPFault with message 'General Protection fault in
module TEST1.EXE at 0000:0171'. Process stopped.
