6311,Broken const-ref semantics,Akim Demaille <akim.demaille@…>,Ion Gaztañaga,"in Boost 1.48, unordered_maps seem to have lost the semantics of constrefs that ""enl4rge your object lifetime"".

The following runs are on a Mac OS X Lion, native clang++ 2.1 and native G++ 4.2.  The latter is completely wrong.  It used to be correct.  Boost 1.48 installed via MacPorts.

{{{
clang++ 2.1
$ /tmp/foo.clang
make_map:   size: 2, bar => BAR, foo => FOO
return_map: size: 2, bar => BAR, foo => FOO
main:       size: 2, bar => BAR, foo => FOO

g++ 4.2
$ /tmp/foo.gcc
make_map:   size: 2, bar => BAR, foo => FOO
return_map: size: 0
main:       size: 0
