Why is that a problem? Jeeze, perhaps you don't like the word perhaps. There is no absolute defect here. There are unnecessary pushes to stack that are unwound by the compiler. Stylistically, format/argument mismatches can cause errors. It's generally bad form and error prone to use non constant strings as formats. Note it's not signed and is a simple suggestion. If you don't like it, don't do anything with it.
