I can reproduce the issue with libc6-armhf-cross 2.28-2cross2 and
qemu-arm-static 1:3.1+dfsg-1, but not with the same binary on real
hardware nor on qemu-user-static 1:2.12+dfsg-3+b1. I would therefore
think it's a qemu bug.

Do you have some other tests showing it's linked to the new upstream
glibc version?
