For me the sassc binary runs fine, and = also the x11-themes/greybird-theme port builds fine. Then again, my base = system is probably older than yours? Which revision are you running? Per my detailed report of gdb session information, I reproduced this via my poudriere-devel build of textproc/sassc in/for the amd64 context: System: # uname -apKU you have mail FreeBSD 7950X3D-ZFS 15.0-CURRENT FreeBSD 15.0-CURRENT #151 = main-n273696-43e045c1733d-dirty: Mon Nov 18 14:46:15 PST 2024 = root@7950X3D-ZFS:/usr/obj/BUILDs/main-amd64-nodbg-clang/usr/main-src/amd64= .amd64/sys/GENERIC-NODBG amd64 amd64 1500027 1500027 # ~/fbsd-based-on-what-commit.sh -C /usr/main-src/ 43e045c1733d (HEAD -> main, freebsd/main, freebsd/HEAD) atf: Guard = libexec/atf with WITH_TESTS_SUPPORT Author: Franco Fichtner <franco@opnsense.org> Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2024-11-18 18:36:46 +0000 branch: main merge-base: 43e045c1733d50fad79f3a53e05140b8dc0d7fa6 merge-base: CommitDate: 2024-11-18 18:36:46 +0000 n273696 (--first-parent --count for merge-base) Ports: # ~/fbsd-based-on-what-commit.sh -C /usr/ports/ ae2ef5f4fb6d (HEAD -> main, freebsd/main, freebsd/HEAD) www/opengist: = Mark as broken on i386 Author: Santhosh Raju <fox@FreeBSD.org> Commit: Santhosh Raju <fox@FreeBSD.org> CommitDate: 2024-11-19 07:07:08 +0000 branch: main merge-base: ae2ef5f4fb6d367a3002c1339d523bc7f8e07e34 merge-base: CommitDate: 2024-11-19 07:07:08 +0000 n686395 (--first-parent --count for merge-base) =3D=3D=3D Mark Millard marklmi at yahoo.com
