--- Comment #12 from Martin Li=C5=A1ka <marxin at gcc dot gnu.org> ---
(In reply to calixte from comment #11)
> Why did you remove __gcov_flush ?

It is not a supported __gcov_* library call:
https://gcc.gnu.org/onlinedocs/gcc/Gcov-and-Optimization.html

You should rather call __gcov_dump and __gcov_reset functions.
