--- Comment #8 from Martin Liška <marxin at gcc dot gnu.org> ---
Ok so the functions like (execve, fork) are recognized as builtins in
non-strict mode:
https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html (Outside strict ISO C
mode...)
I would incline to provide either warning or to include these builtins with
--coverage? Adding gcov maintainers.
