Multi-time initialization of openssl causes the failure of testcase "handshake_server"

[ygo...@gmail.com]

Hi,

    When I run the test case "handshake_server" I randomly got an error of  "double free or corruption","Segmentation fault" or "Hang up", I write a code to regress this issue :

#include <pthread.h>

#include <openssl/ssl.h>

#include <openssl/err.h>

void *server_thread(void *arg)

{

    SSL_load_error_strings();

    SSL_library_init();

    pthread_exit((void *)0);

}

int main()

{

    pthread_t tid;

    printf("OPENSSL_VERSION_TEXT: %s\n", OPENSSL_VERSION_TEXT);

    pthread_create(&tid, NULL, server_thread, NULL);

    SSL_load_error_strings();

    SSL_library_init();

    pthread_join(tid, NULL);

    return 0;

}

I also write a issue in here: https://github.com/grpc/grpc/issues/18900

can you point out weather it is right? thank you!
