You are misreading the CONSTRUCTORS documentation. The a.out object file format is covered under "object file formats which do not support arbitrary sections", and the CONSTRUCTORS command is valid for a.out. We don't bother to mention a.out in the documentation because nobody uses it these days. Technically, in a.out, CONSTRUCTORS tells the linker where to put constructed sets. See ld/ldctor.c. Ian
