The commit adds a regression test which exhibits the exact same behaviour 
as the test case I've sent you. It compiles fine without -std=c++0x, and if 
you compile it with -std=c++0x, it refuses the program with the error 
message "temporary of non-literal type ‘<whatever>’ in a constant 
expression". This seems like a pretty strong connection to me.
