int status;
if (s->qemu_pid != -1) {
kill(s->qemu_pid, SIGTERM);
waitpid(s->qemu_pid, &status, 0);
}
close(s->fd);
close(s->qmp_fd);
g_string_free(s->rx, true);
g_free(s);
}
Not async-signal safe. You need to ignore the g_string_free and g_free
(perhaps even the closes) if calling from the sigabrt_handler.
