while 循环不初始化

Question

我有问题。这是一个处理宽字符串宽度的函数。我的程序在 BREAKPOINT 1 之后进入无限循环。我的循环有什么问题？

static void ft_wstr_width(void)
{
    wchar_t *temp;
    size_t  delta;
    size_t  len;
    size_t  i;
    wint_t  wc;

    len = ft_wstrlen(g_ws);
    delta = (size_t)g_fmt.width - ft_wstrsize(g_ws);
    printf("(%d %zd)\n", g_fmt.width, ft_wstrsize(g_ws));
    temp = (wchar_t *)malloc(sizeof(wchar_t) * (len + delta + 1));
    temp[len + delta] = L'[=10=]';
    if (g_fmt.flags[0])
    {
        wc = (QWSZ ? L'0' : L' ');
        i = 0;
        while (i < delta);
        {
            temp[i] = wc;
            ++i;
        }
        ft_wcopy(temp, g_ws, delta, len);
    }
    else
    {
        printf("[bp0]"); getchar(); // BREAKPOINT 0
        ft_wcopy(temp, g_ws, 0, len);
        i = len;
        printf("[bp1]"); getchar(); // BREAKPOINT 1
        while (i < len + delta);
        {
            printf("[bp2]"); getchar(); // BREAKPOINT 2
            temp[i] = L' ';
            ++i;
        }
    }
    printf("[bp3]"); getchar(); // BREAKPOINT 3
    free(g_ws);
    g_ws = temp;
}

-----UBUNTU 终端输出-----

[bp0]
[bp1]         No reaction here (program keeps running) and
