--- Comment #12 from Martin Li=C5=A1ka <marxin at gcc dot gnu.org> ---
> Do you use it? Or do you use any of -fprofile-dir options?

Ah, ok, you use it. Based on the report:

-fprofile-dir=3Dgcc_prof_dir/%p"

So my recommendation would be not to use it and let GCOV run-time library m=
erge

instrumented run..=
