That is a nice concise log.  The fact that seven 'g++ -c' calls for
compilation seem work yet the the next call to 'g++ -shared ...' for linking
fails makes it seem like an internal compiler error.  g++ is a frontend to ld
et al at that point. And 'man ld' does not mention TMPDIR ...  On the other
hand the error message is still from the compile step.

Are you running with MAKE=make -j8 by chance?

As I said when we hashed this out some more in private mail, I'd try setting
TMPDIR in /etc/profile or alike. Or just try to have a working /tmp directory.
Surely you are not the only AppArmor user with that issue?
