Hi folks,
When running sed 4.9's test suite with -fsanitize=undefined (UBSAN), I get the
following
from make check:
```
FAIL: testsuite/debug
=====================
PATH =
/var/tmp/portage/sys-apps/sed-4.9/work/sed-4.9/sed:/var/tmp/portage/sys-apps/sed-4.9/temp/clang-wrappers:/usr/lib/ccache/bin:/usr/lib/portage/python3.11/ebuild-helpers/xattr:/usr/lib/portage/python3.11/ebuild-helpers:/usr/sbin:/sbin:/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/opt/bin:/usr/lib/llvm/16/bin:/usr/lib/llvm/15/bin:/usr/lib/llvm/14/bin:/var/qmail/bin
