With older gcc and 64-bit size_t, the compiler issues a real warning: rpc/virnetserverservice.c:277: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
Introduced in commit 0cc79255. Depending on machine endianness, this warning represents a real bug that could mis-interpret the value by a factor of 2^32. I don't know why newer gcc didn't bother to warn.
