You called pthread_create() with &threadargs:
ret = pthread_create( &thread1, NULL, mythread, &threadArgs);
when you probably should just use threadargs, since it's already a pointer.
Or else you need to dereference the handle:
post("My symbol: %s",
((*(struct floatArgStruct**))threadArgs)->s->s_name);
