Annex C (informative) Compatibility [diff]

C.4 C++ and ISO C++ 2014 [diff.cpp14]

C.4.11 [containers]: containers library [diff.cpp14.containers]

Affected subclause: [associative.reqmts]
Change: Requirements change:
Rationale: Increase portability, clarification of associative container requirements.

Effect on original feature: Valid C++ 2014 code that attempts to use associative containers having a comparison object with non-const function call operator may fail to compile in this revision of C++.
For example: #include <set> struct compare { bool operator()(int a, int b) { return a < b; } }; int main() { const std::set<int, compare> s; s.find(0); }
