raymond，你好
我按照第三章的fault.cpp书上的代码，在vc2005里面调试，发现执行到__except块后，程序一直不退出，不断打印：
Before div in __try block:nDiviedend=22, nDivisor=0, nResult=100.In __except block:nDiviedend=22, nDivisor=0, nResult=100.Divide Zero exception detected:nDiviedend=22, nDivisor=1, nResult=100.In __except block:nDiviedend=22, nDivisor=1, nResult=100.Divide Zero exception detected:nDiviedend=22, nDivisor=1, nResult=100.In __except block:nDiviedend=22, nDivisor=1, nResult=100.Divide Zero exception detected:nDiviedend=22, nDivisor=1, nResult=100.In __except block:nDiviedend=22, nDivisor=1, nResult=100.Divide Zero exception detected:nDiviedend=22, nDivisor=1, nResult=100.In __except block:nDiviedend=22, nDivisor=1, nResult=100.Divide Zero exception detected:nDiviedend=22, nDivisor=1, nResult=100.……
后来在下载了书上配套的源码，发现和书上不同的是已经把nResult=nDividend / nDivisor; 这一句改成了汇编：
// nResult=nDividend / nDivisor; __asm{ mov eax, nDividend cdq idiv nDivisor mov nResult, eax };
参照配套的源码修改后，vc2005里面程序执行的流程也正常了。请问这可能是什么原因？
