An integer overflow occurs, with the result converted to a wider integer type

Function mongo::storeMongosOptions(const mongo::optionenvironment::Environment &, const std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char>>, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char>>>> &)

Potentially overflowing expression "maxChunkSizeMB * 1024" with type "int" (32 bits, signed) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "uint64_t const" (64 bits, unsigned).

            const uint64_t maxChunkSizeBytes = maxChunkSizeMB * 1024 * 1024;
