- Authentication-results: sourceware.org; auth=none
The function _itoa_word() writes characters from the higher address to
the lower address, requiring the destination string to reserve that size
before calling it.
2017-10-18 Tulio Magno Quites Machado Filho <tuliom@linux.vnet.ibm.com>
* sysdeps/powerpc/powerpc64/dl-machine.c (_dl_reloc_overflow):
Reserve 16 chars to reloc_addr before calling _itoa_word.
