Re: C1001: INTERNAL COMPILER ERROR line 2701

we have a large sln consisting of 95 projects and about 3000 classes.
Lately we ran in all sorts of compiler errors (C1001, C1055 and PRJ0002
with buffer overrun).

For example the following code snippet gives c1001 (/D "_DEBUG" /Gm
/EHsc /RTC1 /MDd /Zc:wchar_t /GR /W4 /WX /c /Wp64 /ZI /TP):

//omitted includes

namespace Tests
{
  struct Foo1234567890 {};

  struct Foo1234567890123456789012345678901234567890;
  typedef Foo1234567890123456789012345678901234567890* KeyType;
}

template <typename T>
struct Container
{
   typedef Tests::KeyType KeyType;
   typedef typename std::pair<KeyType, T> Pair;

   typedef typename boost::multi_index::multi_index_container
           <
               Pair,
               boost::multi_index::indexed_by
               <
                   boost::multi_index::ordered_unique<
boost::multi_index::identity<Pair> >,
                   boost::multi_index::ordered_unique<
boost::multi_index::member<Pair, KeyType, &Pair::first> >,
                   boost::multi_index::ordered_unique<
boost::multi_index::member<Pair, T, &Pair::second> >
               >
           > ImplSet;

   typedef typename ImplSet::nth_index<0>::type Index0;
};

//explicit (DLL) instantiation
template struct TESTS_CLASS Container<Tests::Foo1234567890>;

This is due to the long names and using three indexes with
boost::multi_index. It seems that this boost library touches the limits
of the compiler.

Anyone a clue others than not using boost, stripping long names or
switching to gcc?
