Summary: NPE w/ compound expression

Initial Comment:
such construction raises a NPE.
typedef int uint16_t;

void f() {
        int toto = ({ 
        uint16_t __x;
        __asm__ __volatile__(
                "mov    r2, %0"
                : "=r" ((uint16_t) __x)
                :);
        __x;
        });
}
