When re-writing an
UnresolvedDotExpr
to a resolved member reference, check if the member is a type reference and build aTypeExpr
before checking if the base is a module and building a simpleDeclRefExpr
. Otherwise, CSApply could produce invalidDeclRefExpr
s for a type reference, which will crash later on in SILGen.Resolves: rdar://problem/61450069
