Hi,
when backporting the patch to fix TCP Client Issue a design decision was made
to not use stdatomic.h (as used in 9.14+), but rather use the old ISC atomic
API that we believed was more compatible with existing user base.
Unfortunately, it has slipped our attention that said API lack support for less
common CPU architectures. So far, we’ve been made aware about HP-UX, Solaris
sparc and various fringe Linux architectures.
As immediate remedy to the problem, we are encouraging users to use following
patches:
# BIND 9.11.6-P1
Patch replacing isc_atomic_xadd with isc_refcount API in BIND 9.11:
https://gitlab.isc.org/isc-projects/bind9/merge_requests/1864.patch
The patch will be part of next regular BIND 9.11.7 release.
If by any chance your compiler doesn’t support GNU extensions, you might also
want to apply:
https://gitlab.isc.org/isc-projects/bind9/merge_requests/1826
We introduced this as a fix for alignment problem on Solaris, but it broke
HP-UX.
# BIND 9.12.4-P1
Patch replacing isc_atomic_xadd with isc_refcount API in BIND 9.12.4-P1:
https://gitlab.isc.org/isc-projects/bind9/merge_requests/1879.patch
Please note that BIND 9.12 has reached EOL and there will be only new release
if there’s serious security issue. We hope not.
# BIND 9.14.1
For BIND 9.14.1, a patch would be needed only if you are using GCC with only
the old atomic intrinsic, but here it is anyway:
- https://gitlab.isc.org/isc-projects/bind9/merge_requests/1880.patch
I apologise for the inconvenience this has caused for platforms we don’t have
support for old atomics.

Thanks!
The 1864.patch seems to work fine with Solaris 10 and Solaris Studio 12.2.
It doesn't appear to need 1826.patch.
