Assertion failed in token_iterator.hpp

[nobody]

Using BOOST.1.33.1 with Borland C++.
I've suddenly got a Message Box saying:
Assertion failed:  valid_, file ...boost/token_iterator.hpp, line 52

Line 52 in token_iterator.hpp is:  assert(valid_);  in void increment(){}.

Could anybody give me a clue as to what might be going on and why it has suddenly started happening, please?

With thanks in anticipation,

Looks like you are incrementing past the end of the sequence?
