Summary: Simple compiled program crashes

Initial Comment:
Operating System: Windows 7 64-bit
GCC Version: 4.7.0
Binutils Version: 2.22
MinGW Installer Version: mingw-get-inst-20120426.exe
Build environment: cmd.exe

Minimal Self-Contained Test Case:

Compiling the following segment of code with the command line
g++ main.cpp -o main.exe
will produce an executable file (main.exe). However, upon running the executable file, it will result in the program crashing.

#include <string>

int main () {
    std::string str;

    return 0;
}

I obtained the latest version of GCC by running the installer listed earlier. During the installation process I chose the option "Download latest repository catalogues". Then, under the "Select Components" section, I checked the checkbox next to "C++ Compiler" (everything else left as default). It then downloaded and placed all of the files in C:\MinGW\. However, when I attempt to run a simple compiled program, the program will crash.

I do think this issue has something to do with the version 4.7.0, because when I do not chose the "Download latest repository catalogues" option, it will download and install version 4.6.2 (along with Binutils Version 2.22). I've never had any problems with compiling/running programs with version 4.6.2 on the exact same system setup mentioned earlier.

Running the program compiled with 4.7.0, the following is the crash report that Windows 7 gives:

Message:
Using gcc-4.7.0 and binutils-2.22 I built your program and executed it
without crashing.  I'm not sure what your issue could be.  Here is the
md5sum of my installed libstdc++-6.dll.  Does yours match?
