@leoay ，oldder version 20180427 that u referred works ，thanks so much！

I annotation the line which use mem_sscanf，and unfold mem_sscanf such as below：

// nscan = mem_sscanf(mem, "%256s %256s %d %d", layer_type, layer_name, &bottom_count, &top_count);

{
int _b=0;
int _n = sscanf(mem, "%256s %256s %d %d" "%n", layer_type, layer_name, &bottom_count, &top_count, &_b);
mem+=_b;
nscan = _b>0?_n:0;
}

This fix the problems in my case.
