3855	Xpressive sregex vector fails to compile with gcc 3.4, 4.1	Paul Flew <flewpaul@…>	Eric Niebler	"Hi

I'm trying to use a vector of Boost Xpressive sregex objects. My code is:

#include <vector>
#include <boost/xpressive/xpressive_dynamic.hpp>

using namespace std;
using namespace boost::xpressive;

int main(int argc, char* argv[])
{
       vector<sregex> vec;
       return 0;
}

VS2005 compiles my code successfully, but gcc 3.4.5 and 4.1.2 fail with:

<path>/include/c++/3.4.5/bits/stl_construct.h: In function `void
std::__destroy_aux(_ForwardIterator, _ForwardIterator, __false_type)
[with _ForwardIterator = boost::xpressive::sregex*]':
