--- Comment #11 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Yep, I think the problem is that each of DSOs will have its own set of infos
that will point to its own gcov_merge_add that calls its own gcov_io routines.
Now the winning gcov will walk the list but as soon as it will hit entry from
other DSO it will indirectly call the wrong one.
gcov_merge_add is hidden in my setup.
