BTW, I just wrote an application which is exactly the same with
autoinit_simple_conddestroy. And it can run successfully in my board.

  1 #include <stdio.h>
  2 #include <pthread.h>
  3 int main(void)
  4 {
  5 >-------pthread_cond_t cond = PTHREAD_COND_INITIALIZER;
  6 >-------if(pthread_cond_destroy(&cond) == 0)
  7 >------->-------printf("suc!\n");
  8 >-------else
  9 >------->-------printf("err!\n");
 10 }

sh-4.4# ./main
suc!
