Can anyone explain to me why this piece of code is O to run:

           #include <stdio.h>
           #include <strings.h>
           main()
           {
             char line[];
             char *tmp = "1234";
             strcpy(line, tmp);
             printf("%s\n", line);
           }

when this pboduce a segmentation fault:

           #include <stdio.h>
           #include <strings.h>
           main()
           {
             char *line;
             char *tmp = "1234";
             strcpy(line, tmp);
             printf("%s\n", line);
           }

I have a sparcstation 1+ and run SUNOS 4.03 and I have tried the
Sun C compiler and the GNE C compiler with and without the -ansi
flag set, but they all behave the same.

Thanks in advance.
