There is something unusual in your local environment.
; cat a.c
#include <string.h>
#include <stdio.h>
#include<openssl/rc4.h>

int main()
{
    char code[64]={0};
    char outbuffer[64];
    int codelen = sizeof (code);
    RC4_KEY rc4_key;

    strcpy(code,"This is secrect");
    RC4_set_key(&rc4_key,7,(unsigned char *)"zenraoli");
    RC4(&rc4_key,codelen,(unsigned char *)code,outbuffer);
    memset(code,0,sizeof(code));

    RC4_set_key(&rc4_key,7,(unsigned char *)"zenraoli");
    RC4(&rc4_key,codelen,outbuffer,(unsigned char *)code);
    printf("|%s|\n", code);
    return 0;
}
; gcc a.c -lcrypto
; ./a.out
