AFAICT, the above log is not from a clang build; it is from a GCC build. 
FWIW, I could not find matching clang errors in Jenkins.

With GCC, I can reproduce the -Warray-bounds problem using 
squidcache/buildfarm-fedora-rawhide:latest docker. Thank you, Francesco 
for publishing those! PR 1318 has the proposed fix:
https://github.com/squid-cache/squid/pull/1318


BTW, since GCC v13 has other bugs and has not been officially "released" 
yet, I suggest removing that compiler from the set of required tests 
until it matures enough for us to support it efficiently.


HTH,

Alex.
