basic_string test code with visibility option

Something similar happens when I use GCC option -fvisibility=hidden.

I made a DSO which uses basic_string<>.
And the main function created a basic_string instance with default constructor.
It called a function of the DSO with the basic_string reference in main
function.
Inside the DSO,  the function assigned new string to the reference. Then
it crashes.

I made a simple test code.

For test follow this step:
tar xzf stringtest.tar.gz
cd stringtest
make
./test

then it will be abort with an error.

I tested it on Debian unstable, GCC 4.0.3.
