如前所述，被映射的内存的边界(最后一个有效地址)常被称为系统中断点或者当前中断点。

As mentioned above, the edge of mapped memory — last valid address — is often known as the system break or the current break.

如果要加载自的地址不是一个 16 字节的边界，它就会将该地址的最后四位截断然后再加载，以便使其能够加载。

If it is given an address to load from that is not at a 16-byte boundary, it simply zeroes out the last four bits of the address before loading it so that it will be an aligned load.

暂放下这点不管，问题在于每一个进程运行在自己的地址空间中，而且打破进程边界略微有些不正确性。

Despite the cleverness of the programming, the point is that each Win32 process runs in its own address space and breaking the process boundaries is somewhat incorrect.
