above code:
"/advantage/hlri_tools/sol/SUNWspro/prod/include/CC/Cstd/./vector",
line 318: Warning: should not initialize a non-const reference with a
temporary.
"Test.C", line 302: Where: While instantiating
"std::vector<std::basic_string<char, std::char_traits<char>,
std::allocator<char>>, std::allocator<std::basic_string<char,
std::char_traits<char>, std::allocator<char>>>>::~vector()".
"Test.C", line 302: Where: Instantiated from non-template code.

Kindly help to fix this warning.

Well the culprit line is 318 which you haven't shown.
Anyways the error message is self-explanatory, it is illegal as per standard C++
to initialize a non-const reference with an rvalue.
Some compilers offer it as extension but that's unportable.

Well the culprit line is 318 which you haven't shown.

No, it's line 308 of <vector>.

My advice to the OP is to get a better compiler.

No, I think it's line 318 of <vector>

Quite right.
