The attached reduced code snippet produces an ICE in both GCC 4.8.1 and 4.7.3.
The error messages are respectively:
---
bug.cpp: In substitution of ‘template<class T, template<class ...> class TT,
class ... Args> using bar = void (T::*)(TT<Args ...>&, const symbol_set&) [with
T = Term; TT = Args ...; Args = {Args ...}]’:
bug.cpp:8:86: required from here
