No, that only proves it's compatible enough for gdb to not care. The problem is all those *other* packages that abuse ptrace in totally crackhead ways.

WAY out there.. :) --==_Exmh_1264167798_4668P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFLWat2cC3lWbTT17ARAgw1AKDXe9SH3oEUDuwTIceHaY6I2GlcbwCg4B7Z WdWk82XsrZXGeTOGHXpiUkQ= =2WnU -----END PGP SIGNATURE----- --==_Exmh_1264167798_4668P--
