Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- The error is emitted late when allocating stack space for the array but with optimization we can elide the array. Whatever you try to achieve with this test, you have to do this differently.
