The branch 2026Q1 has been updated by dim: URL: https://cgit.FreeBSD.org/ports/commit/?id=c7b2e561c43524a9cf865fd776672bf19e9ea9cf commit c7b2e561c43524a9cf865fd776672bf19e9ea9cf Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2026-01-23 09:33:18 +0000 Commit: Dimitry Andric <dim@FreeBSD.org> CommitDate: 2026-02-10 19:29:11 +0000 lang/clisp: fix build with clang >= 20 With clang 20 or higher lang/clisp fails to build, with errors similar to: ./lisp.run -B . -N locale -E UTF-8 -Emisc 1:1 -Epathname 1:1 -norc -m 2MW -M interpreted.mem -q -c compiler.lisp -o ./ ;; Compiling file /wrkdirs/usr/ports/lang/clisp/work/clisp-c3ec11bab87cfdbeba01523ed88ac2a16b22304d/src/compiler.lisp ... *** - LIST-INIT-START: start index 44801 too large for (#(NIL #S(HASH-TABLE :TEST STABLEHASH-EQ #:WARN-IF-NEEDS-REHASH-AFTER-GC T (#<BUILT-IN-CLASS SYMBOL> . #<COMPILED-FUNCTION CLOS::MAKE-INSTANCE-<EMF-1>-1>) (#<STANDARD-CLASS FUNCALLABLE-STANDARD-CLASS> . #<SYSTEM-FUNCTION CLOS::%MAKE-INSTANCE>) (#<STANDARD-CLASS STANDARD-CLASS> . #<SYSTEM-FUNCTION CLOS::%MAKE-INSTANCE>))) CLOS::COMPUTE-APPLICABLE-METHODS-EFFECTIVE-METHOD #<STANDARD-GENERIC-FUNCTION MAKE-INSTANCE>) 0 errors, 0 warnings *** Error code 1 The problems are caused by clisp's usage of -fwrapv, where the developers implicitly assume this also makes pointer wrapping defined. After https://github.com/llvm/llvm-project/commit/1295aa2e814 however, -fwrapv no longer implies that, and you either have to add a clang specific -fwrapv-pointer option, or use -fno-strict-overflow, which works for both clang and gcc.
