Sorry, you only show these values for the first iteration. In a loop we need to see whether these values change or not. Most likely the second iteration has the exact same values. In that case we are looking at a rounding issue. It seems like ascender plus descender are bigger than line_height, but when assigning this sum to line_height this condition is still true. Could you please first verify whether this is true and next find out if your computer uses float or double for CGFloat? The next step might then be to get David to look at the assembler code the macro gets converted into.
