Applies to both D1 and D2.

This was caused by svn683, which fixed bug 3602 "ICE(tocsym.c) compiling a
class, if its super class has preconditions"

And the problem is that it's using the scope from the parent function, which
isn't quite right: some of the attributes should be dropped. I don't know if
anything other than STCoverride can cause problems.


func.c, FuncDeclaration::mergeFrequire, line 1688.

        FuncDeclaration *fdv = (FuncDeclaration *)foverrides.data[i];

        /* The semantic pass on the contracts of the overridden functions must
         * be completed before code generation occurs (bug 3602).
         */
        if (fdv->fdrequire && fdv->fdrequire->semanticRun != PASSsemantic3done)
        {
            assert(fdv->scope);
+            StorageClass oldstc = fdv->scope->stc;
+            fdv->scope->stc &= ~ STCoverride;
            fdv->semantic3(fdv->scope);
+            fdv->scope->stc = fdv->scope->stc;
        }

        sf = fdv->mergeFrequire(sf);
        if (fdv->fdrequire)
