Sure..... from the file   <list>  line 278 on my system

#if _HAS_ITERATOR_DEBUGGING
                 void _Compat(const const_iterator& _Right) const
                         {       // test for compatible iterator pair
                         if (_Mycont == 0 || _Mycont != _Right._Mycont)
                                 {
                                 _DEBUG_ERROR("list iterators incompatible");
                                 _SCL_SECURE_INVALID_ARGUMENT;
                                 }
                         }

Looking at the variables  _Mycont == 0 for both *this and _Right
I believe that means an empty list, though I didn't investigate further... 
running UP the call stack we find:

_SCL_SECURE_VALIDATE(_Mycont != NULL && _Mycont == _Right._Mycont);
     g:\program files\microsoft visual studio 8\vc\include\list:262

if (_First == begin() && _Last == end())
     g:\program files\microsoft visual studio 8\vc\include\list:740

return Input.erase( From, To );
     c:\boost\include\boost-_32\boost\algorithm\string\detail\sequence.hpp:56

erase( Input, InsertIt, end(Input) );
     c:\boost\include\boost-1_32\boost\algorithm\string\detail\find_format_all.hpp:247

find_format_all_impl2(
     Input,
     Finder,
     Formatter,
     FindResult,
     Formatter(FindResult) );
     c:\boost\include\boost-1_32\boost\algorithm\string\detail\find_format_all.hpp:177-182

Finder(begin(Input), end(Input)));
     c:\boost\include\boost-1_32\boost\algorithm\string\find_format.hpp:248

const_formatter(Format) );
     c:\boost\include\boost-1_32\boost\algorithm\string\replace.hpp:647

TEST_ALGO( replace_all, "", string("") C_ string("XXXX"), string("") );
     c:\Projects\boost\libs\algorithm\string\test\replace_test.cpp:127

hope that helps
