What do you mean by "dynamic context"? Do you mean that the following 
code does not work?

static struct singleton *singleton = 0;

static void make_singleton(void)
{
    singleton = malloc(sizeof(*singleton));
    // ...
}

void* get_singleton(void)
{
    static pthread_once_t once = PTHREAD_ONCE_INIT;
    pthread_once(&once, make_singleton);
    return singleton;
}
