g++ 2.5.2 does not catch reference to local variable error.

[LIM Fung-Chai]

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.

Regards,
Fung Chai.
