Thanks @eopXD.

What I've seen is that the tst stops crashing for me if I disable all the types starting from line 218 in file `clang/include/clang/Basic/RISCVVTypes.def`.

When it doesn't crash, in my case all the registered RVV types are shown in the output

Curious that you don't observe this. I'll keep investigating.
