test.cpp: In member function ‘void A::fn(const _Pr&) [with _Pr = LT]’:
test.cpp:18:51: instantiated from here
test.cpp:15:4: error: no matching function for call to
‘sort(std::vector<int>::iterator, std::vector<int>::iterator, A::fn(const _Pr&)
[with _Pr = LT]::sub_pred)’
Although I'm not enough of an expert on the STL implementation to determine
whether this program is legal, I do know that this program compiles using the
MSVC implementation of STL.
