Summary: clang crashes on riscv64

I use Debian 11 installed on RISC-V platform: Nezha board with Allwinner D1
processor.
I installed clang as usual: "sudo apt install clang". The version is
1:11.0-51+nmu5. The source of the packages is
http://ftp.ports.debian.org/debian-ports/.
When I run clang from command line without parameters, it crashes with message:
$ clang
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
Stack dump:
0. Program arguments: clang

/usr/lib/riscv64-linux-gnu/libLLVM-11.so.1(_ZN4llvm3sys15PrintStackTraceERNS_11raw_ostreamE+0x28)[0x3fec874c08]

Other compilers seem to work fine. I checked gcc, rustc, go.
