WebJun 2, 2024 · In C, C++, and some other programming languages, the term aliasing refers to a situation where two different expressions or symbols refer to the same object. When references access that object in different ways—as both reads and stores—there are consequences for the order in which these mixed accesses can happen. The value that is … WebJan 14, 2011 · Based on my knowledge, the definition of strict aliasing is that dereferencing pointers to objects of different types will never refer to the same memory location. That would be a pretty useless definition in the context of C or C++. If you have struct S { int n; }; S s; S* pS = &s; int* pint = &s.n;
