[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- Target Milestone|--- |2.059 --- Comment #1 from [email protected] 2012-05-01 11:37:37 PDT --- The root cause is in bigint.d, in the opUnary() function. BigInt uses an underlying BigUint and maps the ++ and -- operators directly through to the BigUint as addition and subtraction, respectively, disregarding the BigInt's sign. However, this is wrong. Signed ++ and -- must be passed through as subtraction and addition, respectively. I modified the function by commenting out the two errant lines and replacing them each with a correct one. This is a proof-of-concept fix for the bug. // non-const unary operations BigInt opUnary(string op)() if (op=="++" || op=="--") { static if (op=="++") { //data = BigUint.addOrSubInt(data, 1UL, false, sign); data = BigUint.addOrSubInt(data, 1UL, sign ? true : false, sign); return this; } else static if (op=="--") { //data = BigUint.addOrSubInt(data, 1UL, true, sign); data = BigUint.addOrSubInt(data, 1UL, sign ? false : true, sign); return this; } } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
