The same package using glibc-2.23 did not have any Unexpected Failures.

Did you show this to glibc folks?
I remember there was something in the newer glibc that caused asan
failures, but that was fixed...

Yes, I saw that glibc entry, but that was back in May and addressed then. glibc-2.24 was released August 5th (5 days ago).

I do not have the background to debug the problem efficiently, but I will open a new bug there.
