Comment 19 for bug 1839592

So, it turns out that 2.27-3ubuntu1.3 could fix this because of the fact that not only does it include that patch, but a full rebase to 2.27 branch of upstream glibc, which does include the other fix mentioned above (I found this out when I tried to rebuild locally and found out that quilt was complaining of an already built patch).

Upon running the code above on the 2.27-3ubuntu1.2 system, it freezes but works fine under 2.27-3ubuntu1.3.
