It does work with older Clang versions, at least through Clang 17.0.6.

See https://gitlab.com/libsir/libsir/-/jobs/6473142110#L91 and https://gitlab.com/libsir/libsir/-/jobs/6473142115#L91 for complete error details.

Verified on a system other than Fedora Rawhide just to be sure it wasn't something Red Hat specific.

Used the Docker image ubuntu:24.04 from Dockerhub (and starting a temporary container docker run --rm -it ubuntu:24.04). Inside the container, I installed packages for libtool autoconf autoconf-archive automake gcc g++ gcc-14 g++-14 clang clang-18 git, and I built and installed OpenOSC master.

Building tests++ target with CXX=g++-13 and CXX=g++-14 both work without problems.

Building tests++ target with CXX=clang++-17 works fine, but CXX=clang++-18 fails with the same symptoms as linked above.

It fails on FreeBSD 14.1 as well.
