--- Comment #5 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Anton Mitrokhin from comment #3) > I see those warnings with -O3, but not with -O0. Why is that? As the documentation says, this warning depends on optimizations. A bogus optimization that breaks the code may thus also cause this warning. > I also do not see what is wrong with the code. If you manage to reduce the example a little more, with fewer lambdas, that might help with the debugging.
