[Bug c++/24852] New: [4.0 regression] Segmentation fault (infinite recursion in cgraph_clone_inlined_nodes)

// compile this with -O3 to get segfault on 4.0.3,
// note the "warning: inline function 'A::~A()' used but never defined".
// 3.3 and 4.1 accept this code without warning.
// This bug was originally reported by Alexey Maximov <amax@mail.ru>
