 Another test case where this happens:
 
 NOTE: The problem occurs on both current snapshot from CVS  and  gdb 6.7
 NOTE2: gdb 6.6 seems to not have this issue.
 
 Compilers tried: 4.1.1, 4.2.1 
 
 Sample code:
 ============= main.cc ====================
 class B {
 public:
 	int b;
 	virtual ~B() {};
 };
 class A: public B {
 public:
 	int a;
 };
 
 int main(int argc, char **argv) {
 	B * b = new A();
 	b->b = 2;
 	A * a = dynamic_cast<A*>(b);
 	a->a = 1;
 }
 ========================================
 
 ====== initcrash =======================
 file test
 -break-insert main
 -exec-run
 -var-create - * b
 -var-list-children var1
 -var-list-children var1.public
 ========================================
 
 To compile:
 g++ -g main.cc -o test
 
 To reproduce assertion:
 gdb -i=mi < initcrash
 
 
 gdb version:
 gdb --version
