Numeric opcodes (OP_1ADD, etc) are restricted to operating on 4-byte integers.

The semantics are subtle, though: operands must be in the range [-2^31 +1...2^31 -1], but results may overflow (and are valid as long as they are not used in a subsequent numeric operation). CScriptNum enforces those semantics by storing results as an int64 and allowing out-of-range values to be returned as a vector of bytes but throwing an exception if arithmetic is done or the result is interpreted as an integer.
