Yes.  From what I remember, part of the reason why glibc 2.28 is not in
the unstable archive "proper" is because of failures in glibc's test
suite, which are really caused by the Linux kernel not cleaning up
properly the state of FP registers between processes.  So they detect
"real" problems :)

Aurélien submitted a patch for it earlier this month to linux-riscv
mailing lists, which hasn't got any replies yet:


Not sure if he's waiting for a resolution to this problem.

The alternative is either retry building and see if in one occasion it
builds fine and the tests pass due to "luck", and the new version gets
added to the archive; or to disable these tests selectively (if
feasible), or disable the test suite completely for riscv64.  In general
we avoided to do the latter, since it helped to find other real problems
also in the past.

Happy New Year/Holidays/etc :)
