According to CPP Reference this is currently not okay: "If expression represents the address A of a byte in memory but A does not satisfy the alignment requirement of T, then the resulting pointer value is unspecified." https://en.cppreference.com/w/cpp/language/static_cast -----Ursprüngliche Nachricht----- Von:organicoman via Std-Proposals <std-proposals_at_[hidden]> No it could not, and it is not allowed. The only thing you will MAYBE get is a misaligned pointer to a double memory location, and you should not dereference that pointer, because of aliasing incompatibility otherwise UB. Try the following code: #include <stdio.h> int main() { char arr[8]; double* ptr = static_cast<double*>(static_cast<void*>(arr+3));
