David Bolvansky ec13f04e8f [Support][JSON][NFC] Silence GCC warning about broken strict aliasing rules ... Summary: The as<T>() method would trigger the following warning on GCC <7: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] return *reinterpret_cast<T *>(Union.buffer); ^ Union.buffer is guaranteed to be aligned to whatever types it contains, and json::Value maintains the invariant that it only calls as<T>() for a T it has previously placement-newed into Union.buffer. This should follow the rules for strict aliasing. Using two static_cast via void * instead of reinterpret_cast silences the warning and presumably makes GCC understand that no strict-aliasing violation is happening. No functional change intended.
