My guess is that you've removed the working directory somehow, or are on a buggy 
filesystem that thinks the working directory has been removed. I can reproduce 
the situation as follows on Ubuntu 16.04.3:

$ cd /tmp
$ mkdir d
$ cd d
$ rmdir /tmp/d
$ LC_ALL=C strace ln -s a b
...
stat("b", 0x7fffe6df6140)               = -1 ENOENT (No such file or directory)
symlink("a", "b")                       = -1 ENOENT (No such file or directory)
...

The only suggestion I have is "don't do that". If memory serves, POSIX doesn't 
specify the behavior in this case.
