Hi,

I can't update the version of one C++ port because now the base clang-34 
fails to find the symbols __ubsan_ (for example __ubsan_vptr_type_cache).
clang36 port compiler fails to find libclang_rt.san-x86_64.a
clang38 port compiler fails to find libclang_rt.ubsan_standalone-x86_64.a

What could be wrong?

Yuri
