This was the result of doing a stage2 asan+ubsan instrumented check-all run.

build setup was like this:

cmake ../llvm -G "Ninja" \
        -DCMAKE_BUILD_TYPE=Release \
        -DLLVM_BINUTILS_INCDIR=/usr/include \
        -DCMAKE_C_FLAGS="-march=native -Og  -g" \
        -DCMAKE_CXX_FLAGS="-march=native -Og  -g" \
        -DLLVM_PARALLEL_LINK_JOBS=1 \
        -DLLVM_OPTIMIZED_TABLEGEN=1 \
        -DLLVM_TARGETS_TO_BUILD="X86" \
        -DCMAKE_AR="${rootDir}/stage_1/build/bin/llvm-ar" \
        -DCMAKE_RANLIB="${rootDir}/stage_1/build/bin/llvm-ranlib" \
        -DLLVM_USE_LINKER="${rootDir}/stage_1/build/bin/ld.lld"  \
        -DLLVM_USE_SANITIZER="Address;Undefined" \
        -DLLVM_PARALLEL_LINK_JOBS=1 \
        -DLLVM_ENABLE_EXPENSIVE_CHECKS=1 

LLVM::BugPoint/named-md.ll failed due to 

llvm/lib/Bitcode/Writer/BitcodeWriter.cpp:3830:16: runtime error: member call
on null pointer of type 'llvm::Module'
