--- Comment #1 from Konstantin Belousov <kib at FreeBSD.org> ---
Yes this is really a libc problem, not rtld. We do not use internal
namespace consistently.
OTOH for malloc(3) related functions, I suspect the decision was deliberate
to make it possible to interpose system implementation with any other user
provided with LD_PRELOAD.
