(it does not help that the ld test for this bug greps for R_*_NONE dynrelocs but not R_*_RELATIVE which i is just as bad for undef weak syms in pie) i added a note to the bug. if you add __attribute__((visibility("hidden"))) to the example given by Rich then it works, the bug only affects static pie linking.
