Description Volker Reichelt 2006-07-31 21:45:53 UTC 
The following (probably valid) code snippet triggers an ICE on mainline:

======================================================================
template<typename T> struct A
{
  struct B;
};

struct C
{
  template<typename T> friend struct __attribute__((packed)) A<T>::B;
};
======================================================================

bug.cc:8: internal compiler error: Segmentation fault
