[Bug bootstrap/64976] Bootstrap fails with -O3 -fgraphite-identity
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64976 --- Comment #2 from hete2 at gmx dot de --- Thank you for this hint. Using this configure option the boootstrapping works. Therefore this report can be renamed to a false warning about -Werror=maybe-uninitialized (if this is considered a Bug) or get closed.
