--- Comment #3 from vincenzo Innocente <vincenzo.innocente at cern dot ch> --- sorry. the original internal bug report was for gcc 7.5 https://godbolt.org/z/9crafbqen where I think the generated code is indeed wrong (and does not depend on the presence of the constructor!) SO, if anything the bug should be changed in: removing constructor inhibit SLP vectorization?
