I do not believe above statement is correct: vdso is most definitely
still returned by dl_iterate_phdr (at least for dynamically-linked
binaries).
The bug is about a "synthetic" entry which glibc started to inject
into fully-static executables somewhere in glibc-2.18 timeframe.
But here we are not dealing with a fully-static executable, and Jared
is using eglibc-2.15 (at least that's what ubuntu 12.04 ships with),
so I think the above bug (and commits associated with it) are
irrelevant.
