在发布模式下无法捕获异常 [英] Can't catch exception in Release mode

问题描述

我无法在程序的发布模式下捕获任何异常.但是调试模式可以正常工作，没有任何问题.我正在使用VS 2008作为我的IDE.

Hi,

I cant catch any exception in Release mode of my program. But debug mode is working fine w/o any problem. I am using VS 2008 as my IDE.

int _tmain(int argc, _TCHAR* argv[])
{
    try
    {
        printf("About to try\n");
        int j,i=20;
        j=i/0;
        *(char *)j = 0000;
        printf("Try done\n");
    }
    catch(...)
    {
        printf("Caught Exception\n");
    }
    printf("Waiting to stop\n");
    Sleep(5000);
    return 0;
}

推荐答案

除以零或访问无效的指针不会导致C ++异常.您可能需要查看结构化异常处理 [

Divison by zero or accessing an invalid pointer do not result in C++ exceptions. You may want to look at Structured Exception Handling[^]

问题在于被零除的问题不会发生.导致抛出C ++异常.如果您确实想捕获此类错误，则可以使用结构化异常处理 [ ^ ](或除C ++异常处理之外).

The problem is that divide by zero doesn''t cause a C++ exception to be thrown. If you really want to catch that kind of error you could use Structured Exception Handling[^] instead (or in addition to C++ exception handling).

感谢您的回复Nemanja Trifunovic和Graham Breach.

我发现了另一个编译器选项，在这种情况下可能会有所帮助.即C ++异常处理和结构化异常处理异常.

Thanks for reply Nemanja Trifunovic , Graham Breach.

I found another compiler option which may be helpful in such cases. ie C++ exception handling with structured exception handling exceptions.
