strtod vs NAN?

[Larry Rosenman]

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="NAN";
  char *border1="/////////////////////////////";
  char *input2="inf";
  char *border2="/////////////////////////////";
  char **ptr;

  num=strtod(input,ptr);
  printf("num=%g\n",num);
  printf("errno=%ld\n",errno);
  printf("ptr=%p, points to %s\n",*ptr,*ptr);
  num=strtod(input2,ptr);
  printf("num=%g\n",num);
  printf("errno=%ld\n",errno);
  printf("ptr=%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!
