>Description:

>How-To-Repeat:

 A sample program is bellow.

#include <stdio.h>
#include <fcntl.h>

int
main(argc, argv)
	int argc;
	char **argv;
{
	int p, pid;
	int c;
	FILE *fp;

	fp = fopen(argv[1], "r+");

	if ((pid = fork()) == 0) {
		while ((c = fgetc(fp)) != EOF) 
			putc(c, stdout);
		exit(0);
	}
	while ((c = getc(stdin)) != EOF)
		fputc(c, fp);
}

 The program output:
% ./a.out /p/tcp/127.0.0.1/daytime
Sun Dec 31 13:51:06 2000
^C

% ./a.out /p/tcp/::1/daytime
^C

>Fix:
  Apply this patch.
