Source: glibc
Version: 2.26-6
Severity: important
Affects: gcc-8 glibc-2.26-*
User: debian-hurd@lists.debian.org
Usertags: hurd
Hi,
glibc versions > 2.25-6 breaks all builds of gcc-8-*/gccgo on GNU/Hurd due to
that -fdump-go-spec is broken.
>From the buildd logs of gcc-8:

The packages in the build environment was downgraded for the failing build and
the only package affecting the build was the libc version.
On gcc-8-8-20171229 the command:
