最新のSAD amorita-snapshot-1410（ないし1400） および main trunk Ver.1.0.10.2.3b3について、PowerMacG5 および MacPro（共にOSはLeopard）を使って、コンパイル最適化レベルを変え（O1、O2、O3）たbench2.sad計算を行いました。
amorita版およびmain trunkともに、PowerMacで最適化レベルをO2ないしO3にすると、掲示板No.531で報告されたEmittance関数の異常が発生します。PowerMacでも最適化がO1なら異常は生じません。また、MacProでは最適化レベルに依らず正常です。ただし、この異常はコンパイルが正常に出来たと見えるときにも生じるので、注意が肝要です。
ついでに、ベンチテスト結果を以下に示します。
