wasi-sdk-33.0 undefined symbols when building with c++ exceptions

[VanillaMaster]

even though wasi-sdk-33 mentions

Build a sysroot that supports C++ exceptions by default

i was unable to compile c++ that uses exceptions to wasm

source file

__attribute__((import_module("env"), import_name("print")))
extern void print(const char*);

struct base {
    virtual void method() noexcept(false) = 0;
};

struct foo : base {
    void method() override {
        print("foo");
    }
};

struct bar : base {
    void method() override {
        print("bar");
    }
};

void destruct(base* object) {
    try {
        object->method();
    } catch (...) {
        print("error");
    }
}

You'll find documentation here how to compile. Looks like -xc++ isn't sufficient, and I don't know why. If you use clang++ it works, however.
