[Comment 1 Paolo Pedroni 2021-06-16 14:49:05 UTC]

On my system clang (and all the toolchain) is built with the following environment variables set:

CC="clang"                            
CPP="clang-cpp"
CXX="clang++"                         
LD="ld.lld"
CFLAGS="-O2 -pipe -frecord-gcc-switches -march=skylake -ftree-vectorize -flto=thin"              
CXXFLAGS="-O2 -pipe -frecord-gcc-switches -march=skylake -ftree-vectorize -flto=thin"
LDFLAGS="-Wl,-O2 -Wl,--as-needed -Wl,--hash-style=gnu -Wl,--sort-common -ftree-vectorize -fuse-ld=lld -flto=thin"
AR="llvm-ar"
NM="llvm-nm"
STRIP="llvm-strip"
RANLIB="llvm-ranlib"
OBJCOPY="llvm-objcopy"
OBJDUMP="llvm-objdump"
OBJSIZE="llvm-size"
READELF="llvm-readelf"

I also tried building sys-devel/clang-12.0.0-r1 with gcc, but the compilation stops at the same point with a different (and much longer) error.

[Comment 3 Paolo Pedroni 2021-06-17 14:14:47 UTC]

Problem was apparently on my end. After building llvm and clang with gcc, and then rebuilding with clang, the failure disappeared.

Closing as INVALID.
