/*To start off, I apologize if this bug already was reported (I didn't find it
mentioned anywhere...). Also, what exactly is meant by 'host triplet', 'target
triplet', and 'build triplet'? (I just sort of guessed at them - I'm assuming
they're the host system and the target system and the system on which the
compiler was built...??) */

/* Simplified test case code (located in main.cpp): */

template<typename B>
class A {
public:
        template<typename C>
        void fn(C c) {
                auto&& key = *c; /* same bug results if 'auto&&' is replaced
with 'auto&' */
        }
};

int main(int argc, char* argv[]) {}

/* Errors produced:
main.cpp: In member function ‘void A<B>::fn(C)’:
main.cpp:6:17: internal compiler error: in type_unification_real, at
cp/pt.c:13310
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

/* The following is the command used to compile the code:
g++ -std=c++0x main.cpp
