1) Download the tarball from the official CVE-2015-7547 tests here:
https://sourceware.org/ml/libc-alpha/2016-02/msg00418.html

2) Comment out BUILDDIR (to build against your system libraries)

3) Run 'make' to build the test, and run them all one-by-one.

Do any of them fail on your system?

Cheers,
Carlos.
