Smaller testcase:

// g++ -O2
#include <string>

// from glibc 2.2.5:

# define bswap_16(x) \
     (__extension__                                                           \
      ({ register unsigned short int __v;                                     \
           __asm__ __volatile__ ("rorw $8, %w0"                               \
                                 : "=r" (__v)                                 \
                                 : "0" ((unsigned short int) (x))             \
                                 : "cc");                                     \
         __v; }))

unsigned short int conv(const std::string &arg)
        {return 1;}

int main(void)
{
        return bswap_16(conv("port"));
};
