--- Comment #6 from anlauf at gcc dot gnu.org --- I couldn't find any current 11-master, 10-, 9- and 8-branch version that fails on x86_64-pc-linux-gnu, under valgrind, and with -m32 and -m64. So it looks very likely that Dominique is right that this has been fixed everywhere. Otherwise please provide more details on your environment.
