Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED CC| |msebor at gcc dot gnu.org Resolution|--- |WORKSFORME --- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> --- I can reproduce the warning with GCC 8 but not 9. GCC 10 doesn't compile the code anymore so I can't test it there. GCC 8 takes 70 seconds to churn through all the code so that's seems too long to reduce it to a small enough test case for an outdated compiler/concepts implementation. Given that -Wuninitialized has lot of known problems, both with and without sanitizers, I'm going to resolve this as WORKSFORSOME.
