- Reply-to: gcc-bugzilla at gcc dot gnu dot org
The following invalid code snippet triggers an ICE on the 4.1 branch
(introduced after 4.1.1) and mainline:
============================================
template<typename T> struct A
{
typedef struct typename T::X X;
};
template<typename T> A<T>::X::X() {}
============================================
bug.cc:3: error: expected identifier before 'typename'
bug.cc:3: error: two or more data types in declaration of 'X'
bug.cc:6: error: ISO C++ forbids declaration of 'X' with no type
bug.cc:6: internal compiler error: in is_ancestor, at cp/name-lookup.c:2247
Please submit a full bug report, [etc.]
Probably related to PR27102.
