This bug was fixed in the package glibc - 2.31-0ubuntu9.9
---------------
glibc (2.31-0ubuntu9.9) focal; urgency=medium
* Disable testsuite on riscv64. It is failing maths tests intermittently in
ways that cannot be a glibc regression and is disabled in later series
anyway.
glibc (2.31-0ubuntu9.8) focal; urgency=medium
* Update for 20.04. (LP: #1951033)
[ Balint Reczey ]
* Cherry-pick upstream patch to fix building with -moutline-atomics
* Prevent rare deadlock in pthread_cond_signal (LP: #1899800)
[ Matthias Klose ]
* Revert: Use DH_COMPAT=8 for dh_strip to fix debug sections for valgrind.
Enables debugging ld.so related issues. (LP: #1918035)
* Don't strip ld.so on armhf. (LP: #1927192)
[ Gunnar Hjalmarsson ]
* d/local/usr_sbin/update-locale: improve sanity checks. (LP: #1892825)
[ Heitor Alves de Siqueira ]
*
d/p/u/git-lp1928508-reversing-calculation-of-__x86_shared_non_temporal.patch:
- Fix memcpy() performance regression on x86 AMD systems (LP: #1928508)
[ Aurelien Jarno ]
* debian/debhelper.in/libc.preinst: drop the check for kernel release
> 255 now that glibc and preinstall script are fixed. (LP: #1962225)
[ Michael Hudson-Doyle ]
* libc6 on arm64 is now built with -moutline-atomics so libc6-lse can now be
an empty package that is safe to remove. (LP: #1912652)
* d/patches/u/aarch64-memcpy-improvements.patch: Backport memcpy
improvements. (LP: #1951032)
* Add test-float64x-yn to xfails on riscv64.
