编译器写道他们指定的寄存器或堆栈区ABI。

The compiler just writes them to the register or stack area specified by the ABI.

对于编译器认为容易出现缓冲区溢出问题的函数，编译器将在堆栈上返回地址之前分配空间。

On functions that the compiler recognizes as subject to buffer overrun problems, the compiler allocates space on the stack before the return address.

因为在发布版本中编译器对堆栈变量进行优化，所以与发布版本相比，堆栈变量在调试版本中仍然为零的可能性更大。

There is a greater chance that stack variables will still be zero in a debug build compared to a release build because of compiler optimizations of stack variables in a release build.
