There are a few known OOM bugs in 3.4, but from the logs it is not immediately apparent if you are hitting those, or if they are new bugs. To be able to figure that out, we need the files mentioned in clang's diagnostic messages, e.g. for arx-libertatis: /tmp/Input-XkKTNq.cpp /tmp/Input-XkKTNq.sh and for supertuxkart: /tmp/engine-11FjEA.cpp /tmp/engine-11FjEA.sh Please put them in a tarball, and upload them somewhere so the bugs can be reproduced without having to clone your entire build environment. -Dimitry --Apple-Mail=_C11C60DA-43FA-4622-BE19-80E712A742D4 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.22 (Darwin) iEYEARECAAYFAlMQoXAACgkQsF6jCi4glqPAFQCfc6yUIt+orPGknAIHTgMD53/p xtsAoNmv25USnHSbLw99WF3ZMTPBMEz5 =H3u5 -----END PGP SIGNATURE----- --Apple-Mail=_C11C60DA-43FA-4622-BE19-80E712A742D4--
