Imagine this:

int foo(void* arg) {
    int v = *(int*)arg; // is arg a potential dangling pointer here?
}

thrd_t t;

int bar() {
   int my_variable = 42;
   int ret = thrd_create(&t,foo,&my_variable);
   return ret;
}

what is the order of execution here? Since foo runs on a different thread and we do not actually wait for the thread to finish/join – but thrd_create returns – is arg a potential dangling pointer?
