I didn't see the email where Ed Schouten commented about seeing my problems of seeing no good stack frames, but Robert, I run only -current here, not RELENG_6, so I can't do the testing you speak of. I would want to see if maybe our gcc on - -current might have been made with a default of emitting no stack frames, which I would guess might have this effect. I guess I could test this, and if it's so, recompile all my libraries to undo that, because I abhor doing things that utterly block any troubleshooting at a minimal savings elsewhere. > > Robert N M Watson > Computer Laboratory > University of Cambridge > _______________________________________________ > freebsd-hackers@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-hackers > To unsubscribe, send any mail to "[EMAIL PROTECTED]" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFIRqLnz62J6PPcoOkRAlhFAJsHrHTMVaFCdPcUha+1yaFOYyMxuACfY+ms jZRd8WCy9PFcwYICmg636y4= =4PYv -----END PGP SIGNATURE----- _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
