--- Comment #13 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to ncm from comment #12) > As it is, your probability of failure in 9 and 10 is exactly 1.0. I don't get this? We speak a possibility that we break a stable release branch by a backport that can somehow interact with other parts of the compiler. The purpose of stable branches is to keep them as stable as possible. This bug is a minor performance issue, not any wrong code or a compiler crash.
