Code in s_tanh.i cause internal error:

extern __typeof (__tanh) tanh __attribute__ ((weak, alias ("__tanh")))
__attribute__ ((__copy__ (__tanh)));; extern __typeof (__tanh) tanhf64
__attribute__ ((weak, alias ("__tanh"))) __attribute__ ((__copy__ (__tanh)));;
extern __typeof (__tanh) tanhf32x __attribute__ ((weak, alias ("__tanh")))
__attribute__ ((__copy__ (__tanh)));
