chunk_alloc第二级配置器的问题

[ArthurDax]

if (!start_free){
obj **my_free_list = 0, *p = 0;
for (int i = 0; i <= EMaxBytes::MAXBYTES; i += EAlign::ALIGN){
my_free_list = free_list + FREELIST_INDEX(i);
p = *my_free_list;
if (p != 0){
*my_free_list = p->next;
start_free = (char *)p;
end_free = start_free + i;
return chunk_alloc(bytes, nobjs);
}
}
end_free = 0;
}
heap_size += bytes_to_get;
end_free = start_free + bytes_to_get;
return chunk_alloc(bytes, nobjs);

当第二级配置器无法在free_list中找到空闲内存时，end_free=0，与《STL源码剖析》对比没有

这样当无可用内存就不会抛出异常，end_free = start_free + bytes_to_get;,会造成错误的水位标识？
