State-Changed-Why:
    Thank you for your bug report.
    
    I cannot reproduce this using 3.2.1:
    
        % cat 8716.cc
        #include <string>
        using namespace std;
    
        int main( int, char** )
        {
            try
            {
                const char* s = NULL;
                string a = string( s, 0 );
                printf( "ok\n" );
                return 0;
            }
            catch( const exception& x ) { printf( "%s\n", x.what() ); return 1; }
        }
        % g++ 8716.cc
        % ./a.out
        ok
        %
    
    Can you try with the lastest release?
    
    I suspect that the fix for 8347 also changed this behavior.
