ld_audit cannot possibly work correctly (because variadic
functions with large arguments are broken, it can cause
runtime crashes) so it is a 'best effort hack' that sometimes
happens to work.

so i'm sad that users depend on it.. possibly because of
false advertisement somewhere that this is a reliable mechanism.
