"avx512bw" argument is broken right now (and will be fixed).
Using a different one works, e.g.:

$ cat pr89929-3.cc
__attribute__((target("sse2", "avx512f"))) int foo(int i) {
        return 1;
}

__attribute__((target("sse3"))) int foo(int i) {
        return 2;
}

__attribute__((target("default"))) int foo(int i) {
        return 4;
}

int main()
{
        return foo(2);
}

$ g++ pr89929-3.cc
[no output]
