[Boost-users] [string/range] 1.34.1 -> 1.35.0 problem

After rebuilding an app with Boost 1.35 (using Visual Studio 2008/VC9 
[creating a 32-bit Unicode executable] on Windows XP SP2), some code (only 
in a release build) calling string_algo causes assertion failures at 
iterator_range.hpp lines 265 and 283 (iterator_range::begin and 
iterator_range::empty).

The assertions are a result of calls to replace_all and istarts_with (in 2
places; each call in different functions and called multiple times from a
single thread; thread data used in the calls is private to this thread).  If
all of these calls are removed:

replace_all(<wstring variable>, L"/", L"\\");

if (istarts_with(<function returning wstring>, <function returning wstring>)
 return;

if (istarts_with(<wstring variable>, L"www."))
 <wstring variable>.erase(0, 4);

the assertions do not occur.  If any or all are left in, some assertions
occur.

When building w/ Boost 1.34.1, the original code works as expected with no
assertions.  Before I try to construct a repro case, does anyone have any 
ideas on what could be wrong?  Thanks.
