(In reply to comment #0)

Extending the testcase shows even more bad behavior in 4.4.3 and earlier:

#include <string>
#include <cassert>

int main()
{
    std::string s1, s2;
    s1.assign(s2.c_str(), 1);
    assert( s1.size() == 1 );

    std::string s3;
    assert( s3.size() == 0 ); // up to gcc-4.4.3 fail here
}
