Does GCC _ever_ > print '0'? No we never print 0. Actually the lines starting with ##### are the interesting that are marked by tools as really not executed: https://gcc.opensuse.org/gcc-lcov/gcc/collect2.c.gcov.html and subject for another coverage. That's why I would like to see function 'iterate' being marked same as foo.
