Isn't strtod supposed to deal with NAN's?

I ran:

$ cat test3.c
#include <stdlib.h>
#include <stdio.h>
#include <errno.h>
int main(int argc,char **argv)
{
  double num;
  char *input=3D"NAN";
  char *border1=3D"/////////////////////////////";
  char *input2=3D"inf";
  char *border2=3D"/////////////////////////////";
  char **ptr;

  num=3Dstrtod(input,ptr);
  printf("num=3D%g\n",num);
  printf("errno=3D%ld\n",errno);
  printf("ptr=3D%p, points to %s\n",*ptr,*ptr);
  num=3Dstrtod(input2,ptr);
  printf("num=3D%g\n",num);
  printf("errno=3D%ld\n",errno);
  printf("ptr=3D%p, points to %s\n",*ptr,*ptr);
  exit(0);
}
$

and I get a SIGSEGV in the first strtod call.

the manpage for strtod implies, to me, that it should deal with it.

Thanks!
