Comment(by Lénaïc Huard <lhuard@…>):

 The issue #3951 is very very similar to this one.

 Like in this ticket, I strongly suspect a bug in latest gcc which
 optimizations break something in the tricks emulating Rvalue references.
 Both issues disappear when the code samples are compiled with latest gcc
 and -std=c++0x or -std=gnu++0x in which case, the Rvalue references are
 managed by the compiler and the boost tricks become useless.
