Uncommenting either of the usages of has_subscript_operator in main causes a crash: sub.cpp: In instantiation of `has_subscript_operator<int>': sub.cpp:13: instantiated from here sub.cpp:6: internal error: Segmentation fault The first line is obviously illegal (a typo I made while I was playing with the testcase), but I believe that the second should be OK. >How-To-Repeat: template<typename T> class has_subscript_operator { private: template <int> struct helper {}; template <class U> static int foo( helper<sizeof( &U::operator[] )> * ); public: int value() { return 0; }; }; int main() { // return has_subscript_operator<int>::value; return has_subscript_operator<int>().value(); } g++ -Wall sub.cc >Fix: Removing the unused template functions (which are unused in this example) from the class avoids the crash. >Release-Note: >Audit-Trail: >Unformatted:
