Attempted to fix it with c81d1df4/OMCompiler but it seems is not what is intended.
What should ExprssionSolve.solveSimpleEquationsWork return for "solved" output variable here?
if not (Types.isIntegerOrRealOrSubTypeOfEither(Expression.typeof(e1)) and Types.isIntegerOrRealOrSubTypeOfEither(Expression.typeof(e2))) then return; end if;
When I set solved := false; it doesn't work with CLANG also.

Fixed in 5e8c11b1932d7bbf72019fc19f62ce4c8a319d7e/OMCompiler.
I'll leave this open so that vitalij or wbraun can check if is correct.

That wired. I think solved := false; should be correct,
but let's wait for vitalijs opinion.
