--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
These are allocation which are handle by loader cache and only shown in
valgrind with the '--show-reachable=yes'.  Since they are cached for the
application, it is expected that loader maintains lingering pointers to the
data and I think it should not be handled a *leaked* memory.

You can check that adding a loop in your program (to dlopen/dlsym/dlclose
multiple times) do not increase the cache usage, as expected.
