FreeBSD-4.0-current from Feb, 17th, 2000

>Description:

Parsing '%+' (time in date(1) format) in strptime dumps core. it works
in 3.4-stable. 

>How-To-Repeat:

Run this standalone program:


#include <stdio.h>
#include <time.h>

int
main(void)
{
  struct tm tm;
  if (strptime("Mon Feb 21 11:20:36 MET 2000", "%+", &tm) == NULL) {
    printf("Parsing failed\n");
    exit(1);
  }

  printf("Time was '%s'\n", asctime(&tm));

  return 0;
}

Result:

#0  0x280c19ee in strcmp () from /usr/lib/libc.so.4
#1  0x2807f0a8 in i386_get_ioperm () from /usr/lib/libc.so.4
#2  0x2807e2e9 in i386_get_ioperm () from /usr/lib/libc.so.4
#3  0x2807f13d in strptime () from /usr/lib/libc.so.4
#4  0x80484b0 in main () at ptime.c:8
#5  0x804842d in _start ()

>Fix:

I'm not sure why this program messes with i386_get_ioperm etc. at all,
so I didn't take a shot at it.
	
Someone who messed with strptime in -current should pick it up.
Thanks.
