Description

What version of protobuf and what language are you using?

Version: v35.1

Language: C++

FreeBSD

LLVM/Clang and libc++ (system's default)

What did you do?

Steps to reproduce the behavior:

I have a Makefile that builds protoc like this:

		echo "$(FMT_HEADER_PREFIX) Configuring protoc sources..."; \
		echo ; \
		echo " - $${SOURCE_DIR}"; \
		echo " - $${BUILD_DIR}"; \
		echo ; \
		"$(CMAKE)" \
			-G "Ninja Multi-Config" \
			-DCMAKE_MAKE_PROGRAM="$(NINJA)" \
			-DCMAKE_CONFIGURATION_TYPES="Release" \
			-DCMAKE_INSTALL_PREFIX="$${STAGE_DIR}" \
			-DCMAKE_INSTALL_LIBDIR=lib \
			-S "$${SOURCE_DIR}" \
			-B "$${BUILD_DIR}" \
			-DCMAKE_PREFIX_PATH="$${ABSEIL_STAGE_DIR};$${ZLIB_STAGE_DIR}" \
			-Dutf8_range_ENABLE_TESTS=OFF \
			-Dutf8_range_ENABLE_INSTALL=ON \
			-Dprotobuf_INSTALL=ON \
			-Dprotobuf_BUILD_TESTS=OFF \
			-Dprotobuf_BUILD_CONFORMANCE=OFF \
			-Dprotobuf_BUILD_EXAMPLES=OFF \
			-Dprotobuf_BUILD_PROTOBUF_BINARIES=ON \
			-Dprotobuf_BUILD_PROTOC_BINARIES=ON \
			-Dprotobuf_BUILD_LIBPROTOC=ON \
			-Dprotobuf_BUILD_LIBUPB=ON \
			-Dprotobuf_DISABLE_RTTI=ON \
			-Dprotobuf_TEST_XML_OUTDIR=OFF \
			-Dprotobuf_ALLOW_CCACHE=OFF \
			-Dprotobuf_FORCE_FETCH_DEPENDENCIES=OFF \
			-Dprotobuf_LOCAL_DEPENDENCIES_ONLY=ON \
			-Dprotobuf_BUILD_SHARED_LIBS=OFF \
			-Dprotobuf_MSVC_STATIC_RUNTIME=OFF \
			-Dprotobuf_WITH_ZLIB_DEFAULT=ON \
			-Dprotobuf_WITH_ZLIB=ON \
			-Dprotobuf_DEBUG_POSTFIX="d" \
			-Dprotobuf_USE_UNITY_BUILD=ON;

What did you expect to see

It should build like older releases e.g. v34.2. But v35.2 fails with the following error.

What did you see instead?

Research direction

Reproduce the failure on FreeBSD 15.0 with LLVM/Clang 19.1.7 using the reported CMake and Ninja configuration, then inspect the first non-warning compiler error in the protoc build output. Confirm the fix by rebuilding the v35.1 sources with the same options and verifying that protoc completes successfully.
