Description
On 64-bit systems, fixnum range can exceed the precision of doubles, which will generate sometimes incorrect results (due to the way overflow is currently detected). +, -, * and / will have to be reimplemented completely differently.

Has been fixed in "overflow-detection" branch and merged into "experimental" to be released as 4.6.3.
