As the result the call "cv::checkRange(m)" that should test for NaN and infinite values always returns "false" (will be workaround-ed).

results of cvRound/cvFloor/cvCeil are not defined if the operands are out of INT_MIN .. INT_MAX range. Adding extra checks for the range will likely slow down the functions dramatically. BTW, it's pointed out in the reference manual.
