    ppc and ppc64 until OPD VDSO function call issues are
    resolved (#1026533).

  - Call gethostbyname4_r only for PF_UNSPEC (#1022022).

  - Fix integer overflows in *valloc and memalign.
    (#1008310).

    functions for ppc (#929302).

  - Fall back to local DNS if resolv.conf does not define
    nameservers (#928318).

  - Add systemtap probes to slowexp and slowpow (#905575).

  - Fix getaddrinfo stack overflow resulting in application
    crash (CVE-2013-1914, #951213).
