The following testcase with invalid virtual inheritance ICEs since GCC 4.0.0:
==================================
struct A
{
virtual ~A() {}
};
struct B : A, virtual A {};
struct C : A, B {};
C c;
==================================
bug.cc:6: error: duplicate base type 'A' invalid
bug.cc:8: warning: direct base 'A' inaccessible in 'C' due to ambiguity
bug.cc: In destructor 'virtual C::~C()':
bug.cc:8: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
A more reduced version crashes since GCC 4.1.0:
==================================
struct A {};
struct B : A, virtual A {};
struct C : B {};
==================================
bug.cc:7: error: duplicate base type 'A' invalid
bug.cc:9: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
