Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Isn't that UB? Both e[0] and e[1] initialized in the first loop when d == 0, but not used there, then e goes out of scope, in the d == 1 iteration e is uninitialized, nothing initializes it and e[0] is returned.
