Especially in the "A debug kernel is not able to show stack traces with cross exceptions anymore. This is because we do not emit any dwarf2 call frame information for any assembler code, since gdb switched to the dwarf2 format" part. And, of course, this work is very important for the community. So, IMO, it will be ok as the target :) Thank you. --=20 Have fun! chd --DocE+STaALJfprDB Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (FreeBSD) iEYEARECAAYFAk2E6roACgkQ0t2Tb3OO/O1xHwCeJRiAVhFQ543+VKtL2KlHyoEg Eo0AnixuK1bF7B4zRsw1oEwh1WnwavIg =qfL4 -----END PGP SIGNATURE----- --DocE+STaALJfprDB--
