--- Comment #3 from Michael Ragazzon <michael.ragazzon at gmail dot com> --- (In reply to Andrew Pinski from comment #2) > std::vector<bool> is a different issue and filed as PR 111118. Thanks for pointing me in the right direction. I believe the warnings in the description points to vector<bool> being used here as well. Perhaps they are duplicates?
