[Bug c++/33842] New: [4.1/4.2/4.3 regression] Broken diagnostic: 'offsetof_expr' not supported by dump_expr

[reichelt at gcc dot gnu dot org]

The C++ generates a broken diagnostic for the following invalid code
snippet since GCC 4.0.0:

=====================================
template<typename T> struct A
{
  A<__builtin_offsetof(T, x)>();
};
=====================================

bug.cc:3: error: type/value mismatch at argument 1 in template parameter list
for 'template<class T> struct A'
bug.cc:3: error:   expected a type, got '#'offsetof_expr' not supported by
dump_expr#<expression error>'
