I'm observing different things:

$ solc --overwrite --bin -o out_dir github.com/ethereum/dapp-bin/library/=/tmp/test_contract --allow-paths /tmp/test_contract/ temp.sol
temp.sol:3:1: Error: Source "/tmp/test_contract/linkedList.sol" not found: File outside of allowed directories.
import "github.com/ethereum/dapp-bin/library/linkedList.sol" as linked_list;
^--------------------------------------------------------------------------^
temp.sol:4:1: Error: Source "/tmp/test_contract/iterable_mapping.sol" not found: File outside of allowed directories.
import "github.com/ethereum/dapp-bin/library/iterable_mapping.sol" as it_mapping;
^-------------------------------------------------------------------------------^

However, just by appending a comma it'll compile:
$ solc --overwrite --bin -o out_dir github.com/ethereum/dapp-bin/library/=/tmp/test_contract/ --allow-paths /tmp/test_contract, temp.sol

@jonnyhsy I think it is the same problem. The problem is that allow-paths doesn't work with a trailing slash.

Hi @axic , I also tried $ solc --overwrite --bin -o out_dir github.com/ethereum/dapp-bin/library/=/tmp/test_contract/ --allow-paths /tmp/test_contract temp.sol; (no trailing slash), it also failed with error

temp.sol:3:1: Error: Source "/tmp/test_contract/linkedList.sol" not found: File outside of allowed directories.
import "github.com/ethereum/dapp-bin/library/linkedList.sol" as linked_list;

Does not work as expected with"." and ".." in Solidity 0.4.19 (0.4.19+commit.c4cbbb05.Windows.msvc).

Working cases:
solc --allow-paths .
solc --allow-paths ./,
solc --allow-paths ../,

Cases that do not work:
solc --allow-paths ./
solc --allow-paths ..
solc --allow-paths ../
