whereas:

sudoku.gcda.good:data:magic `gcda':version `A80e'
sudoku.gcda.good:stamp 46451024
sudoku.gcda.good:tag `00000052' is invalid
sudoku.gcda.good:    00000052:459670006:UNKNOWN

so it looks like the profile data is not usable and hence no pessimization?
That's probably not the fix I was hoping for, oops!
