Hi, "g++ -Wall -Wextra ..." should flag a warning on the following code but does not.
std::pair<int, const XYZ&> get_XYZ_data() { XYZ result; return std::pair<int, const XYZ&>(1, result); } This is a violation of Scott Meyer's "Effective C++" Item 21 "Don't try to return a reference when you must return an object." GCC version 4.5.2 on Kubuntu 11.04 does not issue a warning. I apologize for not subscribing to the mailing list or submitting via GCC Buzilla.
