[Bug tree-optimization/37449] [4.4 Regression] calculix gets wrong answer for -O1 -ftree-pre -ffast-math

--- Comment #1 from janis at gcc dot gnu dot org 2008-09-09 19:51 --- I was wrong in the description, calculix does get wrong results when compiled with -O1 -ftree-pre -funsafe-math-optimizations with r137631, and starts failing with those options sometime between 20080326 and 20080601;
