That looks like a GCC snapshot that's just too old. The version-based header
conditionals work only with released compilers (and later stage 4 snapshots
because of the development wind-down).

This appeared bisecting gcc to find which revision introduced the failure
of malloc/tst-scratch_buffer on hppa:

Shouldn't the prereq for __builtin_dynamic_object_size be GCC 12.1 instead of
12.0?
There's no 12.0 release and the feature was added during the development phase
for the
first GCC 12 release.

AFAICT, except for one instance (in a test not in any headers), version checks
against the first major release always refer to the .0 version number. I guess
this is to make the feature testable during development (where one simply
rebases to the latest gcc development snapshot) so that it remains unchanged in
glibc even after release.

--- Comment #5 from ferdymercury <fernando.hueso at uv dot es> ---
I have found (kind of) a similar problem. I was using nvcc-8 on Ubuntu22, and
after some glibc package upgrades, it stopped working. (see
https://stackoverflow.com/questions/76531467/nvcc-cuda8-gcc-5-3-no-longer-compiles-with-o1-on-ubuntu-22-04).
Now getting: /usr/include/x86_64-linux-gnu/bits/string_fortified.h(104):
error: identifier "__builtin___stpncpy_chk" is undefined
I was wondering if there is a way to hack 'by hand' the string_fortified.h with
an #ifdef guard that checks for the CUDA_version... to restore the original
behavior before the package upgrade.
Thanks!

This looks like something we fixed in 2.36 and backported to the 2.35 release
branch:
https://sourceware.org/git/?p=glibc.git;a=commit;h=478cd506eaa5bbc81e3de6593a5064fa5f36fea9
Ubuntu needs to rebase its release or at least cherry-pick that fix.

Thanks so much for the swift reply. I cherry picked this commit locally, but it
was not enough, I also had to add the following to the ifdef, so that it
entered into the "else", because I am using nvcc-8 compiler together with gcc
(Ubuntu 5.3.1-14ubuntu2):
# if (__GNUC_PREREQ (4, 7) && (!defined(CUDART_VERSION) ||
CUDART_VERSION>8000)) || __glibc_clang_prereq (2, 6)
Now it's working, thanks so much for the hint!
