--- Comment #30 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-01-23 13:30:19 UTC --- What I mean, is a stack PROT_GROWSDOWN RLIM_INFINITY RLIMIT_STACK mapping is defined to be a mapping from the top of that mapping down to the first mapping of something else below it. Whether it is the shadow memory or something else doesn't matter. There is just no overlap in that case, so the error looks wrong to me.
