Hello,

This is a known problem in glibc that has recently been fixed AFAICT.

https://sourceware.org/bugzilla/show_bug.cgi?id=21041

It was also "backported" to the 2.26 release branch:

https://sourceware.org/git/?p=glibc.git;a=commit;h=88758c4ad3f046d050bc2c3ae0f172b6524ca6c2

We currently have 2.26 in 'core-updates' which hasn't started building
yet.  Perhaps we should include this fix, thoughts?
