Comment (by itsme@…):

 it is not only in the thread library, the boost/interprocess library has a
 similar error (invalid initialization of reference type)

 this code builds fine with msvc2010

 with gcc 4.6 beta i get the same error.

 without the -std=c++0x  option it compiles ok

 with boost_1_40_0  and boost_1_39_0 i also get the same error.
