It could still result in an infinity loop
I suggest that you never return a string with unknown length, what happens if src is bigger than 128 ?

swap(& var1, & var2) {
    #emit lref.s.pri var1
    #emit lref.s.alt var2
    #emit sref.s.pri var2
    #emit sref.s.alt var1
}

strscramble(src[], dest[], ssize = sizeof src, dsize = sizeof dest) {
    if(dsize < ssize) {
        return false;
    }
    strcat(dest, src, dsize);
    ssize = strlen(src);
    dsize = 0;

    while(dsize != ssize) {
        swap(dest[dsize], dest[dsize + random(ssize - dsize)]);
        dsize++;
    }
    return true;
}
