WHY is this crashing???!!!

[Robert Angelino]

I have this code that keeps going out to lunch.  Any suggestions
are welcome.

#ifdef vms
	char            cur_time[26];
	const   char    *ptr = (cur_time + 7);
	int             status = 0,
			i = 0;

	$DESCRIPTOR(cur_time_desc,cur_time);
#endif

/* Extract the year from the time */

#ifdef vms
        if(((status = LIB$DATE_TIME(&cur_time_desc)) &1) != 1)
	     return((jtm*)0);

        cur_time[11] = '\0';

#ifdef DEBUG
	printf("ptr = %s\n",ptr);
#endif

        date->tm_year = atoi(ptr);  
#endif

It CRASHES at the "atoi" call.

This is the output I get from the run:

%SYSTEM-F-ACCVIO, access violation, reason mask=04, virtual address=00000014,

These are the logicals I'm using as the libraries:
  "LNK$LIBRARY" = "SYS$LIBRARY:VAXCCURSE"
  "LNK$LIBRARY_1" = "SYS$LIBRARY:VAXCRTL"

I've tried the following and it still crashes:

char *ptr = (char*) 0;
	.
	.
	.

  cur_time[11] = '\0';
  ptr = cur_time + 7;
  date->tm_year = atoi((const char*) ptr);
