I think I discussed this with Robert Watson some time ago and we could use things like ELF hints. But still, that doesn't prevent us from reaching this limitation later on. I think other people (Rink Springer) also reported this issue years ago, even before we had the stack protector enabled. -- Ed Schouten <ed@80386.nl> WWW: http://80386.nl/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEARECAAYFAkoFc1kACgkQ52SDGA2eCwWG6wCeLTizCGSrJjio+5gmA36IEvhw LSIAn1KhfYdQDqqNnaiX04vCYA3Sl3pa =yid8 -----END PGP SIGNATURE-----help
