Bug #: 55843 Summary: ICE after exceeding template instantiation depth Classification: Unclassified Product: gcc Version: 4.8.0 Status: UNCONFIRMED Keywords: error-recovery, ice-on-invalid-code Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: gli...@gcc.gnu.org Hello, the following code, compiled without any option, makes cc1plus segfault. g++-4.7 has a slightly nicer "confused by earlier errors, bailing out". template< typename T > struct type_wrapper { }; typedef char (&yes_tag)[2]; template<bool b> struct if_c { }; template< typename T > struct has_type { struct gcc_3_2_wknd { template< typename U > static yes_tag test( type_wrapper<U> const volatile* , type_wrapper<typename U::type>* = 0 ); }; typedef type_wrapper<T> t_; static const bool value = sizeof(gcc_3_2_wknd::test(static_cast<t_*>(0))) == sizeof(yes_tag); }; template <class K, class T, class=void> struct Get_type { }; struct FT_tag {}; struct RT_tag {}; template <class K> struct Get_type<K, RT_tag, typename if_c< !has_type<Get_type<K, FT_tag> >::value >::type> { }; template <class K> struct Get_type<K, FT_tag, typename if_c< !has_type<Get_type<K, RT_tag> >::value >::type> { }; typedef Get_type<int, FT_tag>::type P;
