Hi, thanks for Clojure! Here's my first contribution (CA filled out and will arrive next week):
Negating Integer.MIN_VALUE overflows but should return a BigInteger. It also affects binary subtraction since Clojure implements it using negation and addition. The overflow occurs silently without throwing an exception. These examples trigger the flaw: user=> (- -2147483648) -2147483648 user=> (- -1 -2147483648) -2147483649 The attached patch is created against trunk r1159. Same examples after applying it: user=> (- -2147483648) 2147483648 user=> (- -1 -2147483648) 2147483647 /Olov Lassus --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
