Yes, this is a know issue. Basically, the error is triggered by a large
amount of [class] template specializations within a single translation unit.
Unfortunatety, while trying to support certain functionalily on broken
compilers, some boost headers contribute a fair amount of those on their own
(please see below). In combination with your own heavy templated code, this
can lead to the errors you've seen.

The simplest one is to split a single translation unit into several ones, if
it's possible.

If it's not, or of this still doesn't help, and you are sure that you are
_not_ using the type_traits type transformation templates
(http://www.boost.org/libs/type_traits/index.htm#transformations), then you
can define (a project wise) BOOST_TT_NO_BROKEN_COMPILER_SPEC macro and see
how this one works out.

Note that for the latter you'll need the latest CVS version of type_traits
library, and that some of the other boost libraries might rely on things
like 'remove_pointer' working properly, so depending on that this might or
might not be a viable option.

HTH,
