By the way, this is a good example of probable "false positives". Consider:
constexpr std::size_t max_size = (sizeof(T1) > sizeof(T2)) ? sizeof(T1) :
sizeof(T2);
This is an example of "legal" code, it could be used for allocating a buffer
which could hold either object of type T1 or type T2. These sizes may be
platform-dependent (or they may depend on template parameters), so this code
makes sence, but it will produce a warning when sizes are equal.
So, probably this warning only makes sence, if ASTs' would be compared, not the
values.
