The errorsome contracts can be found at https://github.com/PolymathNetwork/polymath-core/tree/compilation-bug They are huge because solidity-coverage adds tons of events to track coverage.

To make testing easier, I have added the huge source and compile script to https://github.com/maxsam4/solc-bug-sample with instructions to reproduce.
