That could be quite challenging.  A meaningful test should fail on a
20071031 ld and pass with today's ld.  I think you'd need to replace
ld's memory allocation functions with ones that filled memory with
some non-zero pattern, or run ld under valgrind or somesuch to
reliably detect an error caused by buffer overrun.
