Good day.

I use boost::regex with ICU. When I try call u32regex_match for symbol with code 0xDA10, I get an expression “string iterator not dereferencable (xstring, line 112)”.  If I use other symbol (for example, “X”) it works correctly. If I use wregex (wighout ICU) it works correctly too. What could be the problem?

The code:

#include "stdafx.h"

#include <iostream>

#include <conio.h>

#include <boost/regex.hpp>

#include <boost/regex/icu.hpp>

int _tmain(int argc, _TCHAR* argv[])

{

boost::u32regex delimiterRegex = boost::make_u32regex(L"\\W");

std::wstring symbol = L"X”;

symbol[0] = wchar_t(0xDA10); // <= for this symbol

if (boost::u32regex_match(symbol, delimiterRegex)) // <= assertion here

std::cout << "success" << std::endl;

else

std::cout << "not match\n";

_getch();

return 0;

}

I checked it for boost_1_47_0.

MSVC 2008 compiler.

Thank you in advance,
