solc 0.4.17 compile errors for pure functions

With the truffle 4 beta 2 release which includes the solc@0.4.17 upgrade instrumented contracts containing functions decorated with view will generate a Warning, while those marked as pure will Error with

TypeError: Function declared as pure, but this expression (potentially) reads from the environment or state and thus requires "view".

This is due to the SC instrumented function containing events (which modify state) being present in the pure function.

I seem to be facing the same issue with 0.5.8.

/project/coverageEnv/contracts/MyContract.sol:237:5: TypeError: Overriding function changes state mutability from "view" to "nonpayable".
    function allowance(address owner, address spender) public  returns (uint256) {emit __FunctionCoverageMyContract('/project/coverageEnv/contracts/MyContract.sol',12);
    ^ (Relevant source part starts here and spans across multiple lines).
openzeppelin-zos/contracts/token/ERC20/ERC20.sol:11:3: Overriden function is here:
  function allowance(address owner, address spender) public view returns (uint256);
  ^-------------------------------------------------------------------------------^

MyContract.sol inherits from openzeppelin-zos/contracts/token/ERC20/ERC20.sol and implments the allowance function with the same signature.

function allowance(address owner, address spender) public view returns (uint256) {
     // IMPL     
 }

Thanks @cgewecke Compilation failed for me in the following scenario: Contract inhering from another which lives outside the /contracts folder, e.g. a git submodule library for me specifically it looks like this:

/contracts/Token.sol
/lib/dappsys/erc20.sol

This generates compile error:

/coverageEnv/contracts/Token.sol:25:5: TypeError: Overriding function changes state mutability from "view" to "nonpayable".
    function totalSupply() public returns (uint256) {__FunctionCoverageToken('/contracts/Token.sol',1);
    ^
Spanning multiple lines.
/coverageEnv/lib/dappsys/erc20.sol:23:5: Overriden function is here:
    function totalSupply() public view returns (uint supply);
    ^-------------------------------------------------------^
