warning: dereferencing type-punned pointer will break strict-aliasing rules A: 在高优化级别下,gcc假定不同类型指针不会指向同一片内存,以加强优化,从而可能导致编译出不符合原意的代码。 使用-fno-strict-aliasing,关闭在此类代码上的优化。

Dereferencing a null pointer is frequent problem in C and C++. We have several checks to deal with such problems. See thisblog postfor a comparison. When the analysis engine deduces the value of a pointer to be null and sees that pointer get dereferenced, it will emit aC26822warning. You...
