--- Comment #1 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
This looks like a miscompilation of the stage #2 compiler, so probably no way
to debug this except on a x32 machine.

Corresponding Debian issue: https://bugs.debian.org/988305

Debian's kernel support for x32 syscalls can be activated, and then you can
install a x32 chroot. See https://wiki.debian.org/X32Port.  Ubuntu's kernel
also has the x32 syscalls.

Can you retry with current trunk?  There have been several fixes.
