In the meantime, could you share your gcc with me so I can see what the contents looks like? This is mine: https://media.marusich.info/gcc-stripped-5.5.0-powerpc64-linux-gnu.tar.xz Hopefully we can pinpoint the source of the non-determinism and fix it! =2D-=20 Chris --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEy/WXVcvn5+/vGD+x3UCaFdgiRp0FAl7Wo9YACgkQ3UCaFdgi Rp3KOw//dhk90f0igxYLOqbk0tIpT6sWm3twPxOaclXynP5nsCH3f6ulWwoDAkzd dCvpygP38P/gDU1xV9mvpcwMmlFob4BWP6zHMVCvgrzzJTpoznfBqpVG5dLXixc8 pUd/o3stYy5tc69IyC5B2j1jTlnQPAJe5XZaiTqsd9WUTuxuUc+xCGXWVIn+LAqs BqgufXZWbMzo6LQ6Wi2/JkdzAAIQhVOnJJk6oI0gQZYZNw3s0T8U++dntrvQObJt hVYUxSq5kPclpvxhGMwLq1P/pjPKKn/tYrsXHXjeA/TAvzRjPd3PaIvq+8un8yf3 UjG9mvmAo+0cPR4ZduiYSuxUOgzeS/oS3vBF0DgzrfJ37PTcbZzHQwazxWmzGo6M cO2BAOLIRNKteFMaqyEnfmIYBun3SyBNk/uYfsJYU8q9/3uLkIGbm+1TqMpdwZnv UBrS8KvLCWGEOgL4m+BgXrHqV1o0dbdjSW8f2p+yAlbUYiFJg+jCZzs1EhemiC+F fu5JlV+CsFvTPcDLxt8lXteYvUfHG4UUs45oT8hcYMlHBvpnSOO4h4mK3ZZXOjIt f9LVJpG0GI5aX+5LfZPqHj0Ai1Quu8TuIc0d4q4B0cxcdFaJujgNi3Mermf7Fi5x pTRqqqWR2SGiUof0DZ2s7CEXd6ffOa/snHzEck/prWZjKXv9GcI= =gC8B -----END PGP SIGNATURE----- --=-=-=--
