Hi, digging around I found one of the first programs ever written. It's an static aout binary from 1994 or so, running it on FreeBSD 8.2 shows exactly this problem. Some more extensive tests narrowed this problem down to FreeBSD 1.x binaries, they're all broken. FreeBSD 2 aout binaries are still working.=20 Since Google found this rather old thread I decided to provide the data your requested, but I do not insist on a fix. I guess that nobody will try to run FreeBSD 1.x binaries these day... So if you want to spend some work on this I'll test patches but if you decide to do nothing it's okay. This is the /bin/sh of FreeBSD 1.0 (taken from the official installation cd image f=FCr i386): % file sh sh: VAX demand paged pure executable % ./sh Abort The ktrace / kdump: 1065 ktrace RET ktrace 0 1065 ktrace CALL execve(0xbfbfee1b,0xbfbfecf8,0xbfbfed00) 1065 ktrace NAMI "./sh" I've uploaded the binary to: http://deponie.yamagi.org/freebsd/tmp/sh_freebsd1 Thanks, Yamagi --=20 Homepage: www.yamagi.org XMPP: yamagi@yamagi.org GnuPG/GPG: 0xEFBCCBCB --Signature=_Sun__4_Dec_2011_20_54_27_+0100_aeM58VjxTMJ7ni0n Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk7bz/gACgkQWTjlg++8y8seswCeMEdxBzGv0IQiLHBHos0SFLtx 5LAAnj9DRPeG+lf4WH3g/FU3mJbkJ5f9 =BHto -----END PGP SIGNATURE----- --Signature=_Sun__4_Dec_2011_20_54_27_+0100_aeM58VjxTMJ7ni0n--
