The regset_data buffer allocated with calloc() in the parent process of several vector ptrace tests is never freed before returning, causing memory leaks in:
- ptrace_v_not_enabled - ptrace_v_early_debug - ptrace_v_syscall_clobbering - v_csr_invalid/ptrace_v_invalid_values - v_csr_valid/ptrace_v_valid_values Add free(regset_data) before kill(pid, SIGKILL) to release the allocated buffer.
