Ref AntelopeIO#99: Add test

This test fails without the fix to issue AntelopeIO#99, and passes with it.
The failure is a bit odd -- it doesn't fail because cdt-cpp crashes;
rather, it fails because the crashed cdt-cpp did not output an abi
file and therefore it cannot match the golden record... But hey, it
does test the issue, just rather indirectly. =)
