           Summary: clang ToT can't parse boost::addressof any more
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: richard-llvm at metafoo.co.uk
                CC: llvmbugs at cs.uiuc.edu, dgregor at apple.com


This code (simplified from boost::addressof) stopped compiling with clang ToT
in the past day or so:

template<typename T> void a(T c) {
const_cast<char&>(reinterpret_cast<char&>(c)); }


It fails as follows:

$ clang++ clang-addressof.cpp
clang: <...>/clang-svn/lib/AST/ExprClassification.cpp:69: Cl
clang::Expr::ClassifyImpl(clang::ASTContext&, clang::SourceLocation*) const:
