The following testcases cause ICEs since GCC 3.4.2:
=======================================================================
template<typename> struct A
{
template<typename T> friend void* A<T>::operator new();
};
A<int> a;
=======================================================================
bug.cc:3: error: 'operator new' takes type 'size_t' ('long unsigned int') as
first parameter
bug.cc:3: error: invalid template declaration of 'static void* A<T>::operator
new(long unsigned int)'
bug.cc: In instantiation of 'A<int>':
bug.cc:6: instantiated from here
bug.cc:3: internal compiler error: in tsubst_decl, at cp/pt.c:6360
Please submit a full bug report, [etc.]
=======================================================================
template<typename> struct A
{
template<typename> friend void* operator new(__SIZE_TYPE__);
};
A<int> a;
=======================================================================
bug.cc:3: error: invalid template declaration of 'void* operator new(long
unsigned int)'
bug.cc:3: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
The ICEs were fixed on mainline by the patch for PR 27559.
I'll test a backport for the 4.1 branch and the 4.0 branch.
