https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=295800 Bug ID: 295800 Summary: llvm 21.1.8 breaks buildworld with WITHOUT_INET6=yes Product: Base System Version: 14.4-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: john@cybersashi.com Created attachment 271429 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=271429&action=edit Patch to workaround issue. Since the update to LLVM 21.1.8 doing a buildworld of stable/14 with WITHOUT_INET6=yes results in: /usr/src/usr.sbin/inetd/inetd.c:1377:44: error: variable 'nbuf2' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer] 1377 | rpcb_set(sep->se_rpc_prog, i, netid2, &n buf2); | ^ ~~~~ In March (i.e. prior to llvm 21.1.8) buildworld worked fine. With the attached patch the buildworld succeeds using llvm 21.1.8. Strictly speaking given the original code of: struct netconfig *netid, *netid2 = NULL; ... #ifdef INET6 ... #endif ... if (netid2) { rpcb_unset(sep->se_rpc_prog, i, netid2); rpcb_set(sep->se_rpc_prog, i, netid2, &nbuf2); } It seems like the rpcb_set should be unreachable code with WITHOUT_INET6=yes so the llvm error is a false positive, however patching inetd was a quick fix. -- You are receiving this mail because: You are the assignee for the bug.home | help
