llvm-23 needs updates for the symbols files. This is RC, because once
packages start building using LLVM 23, and using these new symbols,
there's no way to hinder these to migrate and trying these packages to
use the shared libraries from llvm-22.

  - debian/libclang1-23.symbols needs an update, but is not
    RC, because it's a new shared library.

  - libomp5, libc++abi1 have these additional symbols.

  - libc++1 has additional symbols, but also some missing symbols.
    These need to be checked, if they are optional.

We believe that the bug you reported is fixed in the latest version of
llvm-toolchain-23, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1147194@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.

Closes: 1147194
Changes:
 llvm-toolchain-23 (1:23.1.1-2) unstable; urgency=medium
 .
   * Refresh the symbols files from the 1:23.1.1-1 buildd logs
     (libc++1, libc++abi1, libomp5) and add the LLVM_23 symver to
     libclang1-23. (Closes: #1147194)
   * libc++1: drop the five (subst) template entries added in 22. (subst)
     and {size_t} are pkg-kde-tools extensions and this package does not
     build-depend on it, so plain dpkg-gensymbols never matched them and
     reported them as both missing and new on every build. They are
     replaced by explicit arch-bits=32/64 entries.
   * libc++1: mark _ZNSt3__18ios_base9__xindex_E@Base optional, it is a
     private libc++ internal removed upstream in 23.
