Description of problem:
I've been able to get g++ to crash when a method of a class is called that 
new's an instance of a class that is defined within the method, and where this 
locally defined class does not have a destructor and the class it is derived 
from has a virtual destructor.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Put the following code into a file named "test.cpp" (this is small enough 
that I thought I could include it here):

    class BaseClass
    {
    public:
        virtual ~BaseClass () {};
    };

    class Test
    {
    public:
        static void Foo()
        {
            class LocalClass: public BaseClass 
            { 
            public:
                // ~LocalClass() {};
            };
            new LocalClass;
        }
    };

    main() 
    {
        Test::Foo();
    };


2. Compile it as follows:

    g++ -Wall -g -O -c -w -D_REENTRANT -Wunused -fsigned-char 
    -fsigned-bitfields test.cpp

Actual Results:  The following message was displayed:

    test.cpp: In method `Test::Foo ()::LocalClass::~LocalClass ()':
    test.cpp:24: Internal error: Segmentation fault.
    Please submit a full bug report.
    See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions.


Expected Results:  The code should have compiled without errors.

Additional info:

The workaround for this problem is to write a destructor for LocalClass.  While 
this fixes the problem, it is completely unnecessary to have a destructor in my 
case.
