      Overflowed constant

      The overflowed value due to arithmetic on constants is too small or unexpectedly negative, causing incorrect computations. Integer overflow occurs in arithmetic on constant operands
      /src/mongo/db/storage/key_string.cpp:2678: INTEGER_OVERFLOW 170504 Expression "remainingBytes - 1U", which is equal to 4294967295, where "remainingBytes" is known to be equal to 0, underflows the type that receives it, an unsigned integer 32 bits wide.
