小编roh*_*ren的帖子

这是我的代码片段.

int main()
    {
    int *var = new int(6);
    cout<<"Hello\n";
    delete var;
    return 0;
}

当用mudflap编译时

$export MUDFLAP_OPTIONS="-print-leaks -mode-check"
$g++ test.cpp -fmudflap -lmudflap
$./a.out
Segmentation fault (core dumped)

但是在没有mudflap选项的情况下进行编译时,它不会抛出核心转储.我是mudflap的新手.请告诉我是否以错误的方式使用mudflap.

供参考:

核心由`./a.out'生成.
