tried with SSL mutex callbacks ...

#include <pthread.h>
#include <openssl/crypto.h>
static pthread_mutex_t* __ssl_mutex = NULL;

static void __ssl_locking(int mode, int n, const char* file, int line)
{
    if (mode & CRYPTO_LOCK)
        pthread_mutex_lock(&__ssl_mutex[n]);
    else
        pthread_mutex_unlock(&__ssl_mutex[n]);
}

static unsigned long __ssl_threadid(void)
{
    return ((unsigned long)pthread_self());
}

void __ssl_mutex_init()
{
    __ssl_mutex = (pthread_mutex_t*)OPENSSL_malloc(CRYPTO_num_locks() * sizeof(pthread_mutex_t));

    for (int i = 0; i < CRYPTO_num_locks(); i++)
    {
        pthread_mutex_init(&__ssl_mutex[i], NULL);
    }
    CRYPTO_set_id_callback(__ssl_threadid);
    CRYPTO_set_locking_callback(__ssl_locking);
}

and in init() ...

    curl_global_init(CURL_GLOBAL_ALL);

    __ssl_mutex_init();

but still see failures ...
