Technically, this program produces undefined behavior, as the last thing
output does not end in '\n', so I wouldn't says your compiler is "broken".
But, if that's really what you get, it's probably seriously funky.

The above program is equivalent to:

int main()
 {
   printf("d",123);
   return(0);
 }

On most systems, you would probably end up with a single lower-case "d"
being output.  Others would probably end up with no output at all.

For example, my Unix system shows:

# cc -o foo foo.c
# ./foo
d#
