<pre>I can reproduce by:
1. Installing LLVM 13.0.0rc1 to the system (static libs/dylib don't seem to
matter).
2. Build clang against it:
cmake .. -G Ninja -DCMAKE_BUILD_TYPE=MinSizeRel
-DLLVM_MAIN_SRC_DIR=/home/mgorny/git/llvm-project/llvm
-DLLVM_TOOL_CLANG_TOOLS_EXTRA_BUILD=OFF
ninja check-clang
The tests used to pass 100% in 12.0.1. They also pass in a combined LLVM+Clang
build. I haven't been able to pinpoint a specific difference between these two
builds.
The test failures are:
