result[numchars++] = basechars[r];

When you're done, print from numchars-1 back down to 0 (one char at a time).

when I add the result[i++] the program crashes, I think because it keeps incrementing infinity

You're making this more difficult than it needs to be. Look at this code snippet:

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
    while (d != 0) {
        r = d % b;
        d = d / b;
        result[len++] = basechars[r];
    }
 
    for (i = len-1; i >= 0; --i) {
        printf("%c", result[i]);
    }
    while (d != 0) {
        r = d % b;
        d = d / b;
        result[len++] = basechars[r];
    }

    for (i = len-1; i >= 0; --i) {
        printf("%c", result[i]);
    }
