Component: kernel
Migrated from: https://bugs.erlang.org/browse/ERL-194

---

When adding a code path ending with "ebin" and with 2 levels, erlang crashes, for example:
{code}
$ erl -pa /myproject/ebin
2016-07-14 12:44:06 Error in process ~p with exit value:~n~p~n
	<0.36.0>
	{{case_clause,[]},[{code_server,split_base,1,[{file,"code_server.erl"},{line,639}]},{code_server,archive_subdirs,1,[{file,"code_server.erl"},{line,825}]},{code_server,do_insert_name,3,[{file,"code_server.erl"},{line,819}]},{code_server,init_namedb,2,[{file,"code_server.erl"},{line,794}]},{code_server,init_namedb,1,[{file,"code_server.erl"},{line,790}]},{code_server,init,3,[{file,"code_server.erl"},{line,96}]}]}

$ erl
Erlang/OTP 19 [erts-8.0] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V8.0  (abort with ^G)
1> code:add_path("/myproject/ebin").
{"Kernel pid terminated",error_logger,badarg}

Crash dump is being written to: erl_crash.dump...done
Kernel pid terminated (error_logger) (badarg)
{code}

But there is no problem if the path doesn't end with "ebin":
{code}
$ erl
Erlang/OTP 19 [erts-8.0] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V8.0  (abort with ^G)
1> code:add_path("/myproject/test").
true
{code}

I'm creating a pull request to fix this.
