The following piece of code crashes both my custom built gcc 4.0.0 (straight
from an official mirror) and gcc 4.0.0-0.41.fc3 from Red Hat. The code is a
reconstruction of a piece of propriatary code I cannot post.
CODE:
typedef unsigned int size_t;
class A;
class B;
class C;
template<class _T> inline void* operator new( size_t Size, _T&);
template<class _T> inline void operator delete( void*, _T&);
class Abase {};
class A : public Abase {
public:
A() {}
A(int a, int b, int c, int d) {}
};
class Bbase {};
class B : public Bbase {
public:
Abase* m() {
return new(a) A(1,2,3,4);
}
A a;
};
class C {
public:
Bbase* n() {
return new B();
}
};
GCC OUTPUT:
main.cpp: In member function ‘Bbase* C::n()’:
main.cpp:29: internal compiler error: Segmentation fault
