The ptrace_v_not_enabled test expects the child to reach its ebreak before it has used the vector extension. That is not guaranteed when using fork(), because libc may run child atfork handlers before returning to the test code. In those cases PTRACE_GETREGSET for NT_RISCV_VECTOR then succeeds instead of returning ENODATA for inactive vector state. Use the raw clone syscall with SIGCHLD to keep fork-like semantics while bypassing libc's fork wrapper and atfork handler chain.
