Description
When trying to write more than 2GiB of data to a QBuffer on 64-bit platforms, the write() call returns success, while the write is actually short:
const std::string input(2 * 1024 * 1024 * 1024 + 1, 42); auto r = buffer.write(input.data(), input.size()); // returns input.size() // but assert(buffer.buffer().size() == input.size()); // fails!
32-bit platforms don't support this operation, so it's a 64-bit-only issue.
