Testcase
Hi,
I get an ICE with the attached test case when I compile with -std=c++11.
I'm using GCC 4.8.1 from Debian experimental (x86_64). The ICE happens with
4.7.3 too.
I don't get the ICE when I change the line to
int i(B::goo(t));
int const i = B::goo(t);
Cheers,
André

Trivial configure-time check

Okay, so I guess there's no alternative but to disable libsanitizer for these
systems.
I see that libsanitizer support is inferred automatically by the
libsanitizer/configure.tgt script, which is sourced from the top-level
configure script. This script is not processed by Autoconf, so doing a
test-compile in there would be somewhat awkward. However, on this old Debian
system, the linux/futex.h header doesn't exist at all, so picking up on that
would be enough for me.
See attached patch for a first-draft proposal. (There probably needs to be some
build/host/target-sysroot awareness of where to look for the header; I'm not
familiar enough with building cross-compilers.)

Note that it is triggered by the 'using', if you replace the mapping by
template <typename T> struct map { typedef const T type; };
and adapt 'apply' like this:
template <
template <typename...> class F,
template <typename...> class L, typename... T
> struct apply <F, L <T...> > { typedef L <typename F <T>::type...> type; };
the result changes to the expected:
undefined reference to `void dummy<A<int const> >()'
