cc1plus: all warnings being treated as errors
Here is the relevant bit of test:
template<class Builder>
void builder_move_assign_after_releaseraw_test(Builder b1) {
auto root_offset1 = populate1(b1);
b1.Finish(root_offset1);
size_t size, offset;
std::shared_ptr<uint8_t> raw(
b1.ReleaseRaw(size, offset), [size](uint8_t *ptr) {
flatbuffers::DefaultAllocator::dealloc(ptr, size);
});
Note how `b1.ReleaseRaw(size, offset)` is expected to populate `size`
and `[size](uint8_t *ptr) {` captures the result. But both are parameters
to the same function call and thus evaluation order is unspecified.

FlatBuffers
FlatBuffers is a cross platform serialization library architected for maximum memory efficiency. It allows you to directly access serialized data without parsing/unpacking it first, while still having great forwards/backwards compatibility.
