--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I believe that instruction is power9 only, on the other side
_GLOBAL__sub_I_eh_alloc.cc doesn't come from the code you were compiling, b=
ut
from libstdc++.a(eh_alloc.o).
So, it depends on how the gcc you are using has been compiled.
If it is from an Ubuntu package, you need to report it to Ubuntu.=
