Interestingly (in a bad way!),
this regression may be related to a problem that Stephan just reported. See:

https://bugzilla.yoctoproject.org/show_bug.cgi?id=15647

It seems that the problematic commit is:
a180e82837 Linux: Make __rseq_size useful for feature detection (bug 
31965) but let's get that confirmed in the bug report.


The lesson learned is that if there's a regression from a glibc update 
even a single intermittent failure,
we should spend more time investigating the problem.

Deepthi did re-run the tests both manually and as part of the test suite 
only to find that the issue
was not reproducible but in hindsight, we could have done more.

We'll work on improving our testing.
