--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> --- > do_it() is indeed called 4 times,but I wonder how the coverage statistiscs > of the for-statement is calculated. It doesn't become 5 untill the > for-stamentment is completed. We count a line every time there exists a jump from a different line that jumps to the line. Thus for `for(;;)` there are no statements we should jump to.
