core dump happened in bicubic_resize. dbg core_file reports like

I added some logs like this:

int src_buf_size = img.buf.size();
    for (i = 0; i < target_height; i++) {
        for (j = 0; j < target_width; j++) {
            x = (int)(tx * j);
            y = (int)(ty * i);

            dx = tx * j - x;
            dy = ty * i - y;

            for (k = 0; k < 3; k++) {
                for (jj = 0; jj <= 3; jj++) {
                    int temp = (clip(y - 1 + jj, 0, ny - 1) * nx + clip(x, 0, nx - 1)) * 3 + k;
                    if (temp >= src_buf_size) {
                        LOG_TEE("%s: temp %d, src_buf_size %d\n", __func__, temp, src_buf_size);
                    }

                    d0 = img.buf[(clip(y - 1 + jj, 0, ny - 1) * nx + clip(x - 1, 0, nx - 1)) * 3 + k] - img.buf[(clip(y - 1 + jj, 0, ny - 1) * nx + clip(x, 0, nx - 1)) * 3 + k];
                    d2 = img.buf[(clip(y - 1 + jj, 0, ny - 1) * nx + clip(x + 1, 0, nx - 1)) * 3 + k] - img.buf[(clip(y - 1 + jj, 0, ny - 1) * nx + clip(x, 0, nx - 1)) * 3 + k];
                    d3 = img.buf[(clip(y - 1 + jj, 0, ny - 1) * nx + clip(x + 2, 0, nx - 1)) * 3 + k] - img.buf[(clip(y - 1 + jj, 0, ny - 1) * nx + clip(x, 0, nx - 1)) * 3 + k];
                    a0 = img.buf[(clip(y - 1 + jj, 0, ny - 1) * nx + clip(x, 0, nx - 1)) * 3 + k];                     

it outputs:

bicubic_resize: temp 5113152, src_buf_size 5092990

does this mean it will cause the access of img.buf[] in following lines will cause invalid access?
