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.
