Yes. See the code below.

This test case fails in the described way. It seems to be because I use a smatch when an
cmatch should be used instead!? With no stlport this (kind of) code works fine.

using namespace std;
using namespace boost;

void test_regex()
    char const * s_line = "String";

    boost::smatch m;
    if (regex_match(s_line, m, regex(".*")))
        string s = m[1];

int main()
    return 0;
