I compiled your code (after removing the logging stuff),  and it worked
fine under Warp with Cset++ 2.1 (csd CT00011 applied).  
 
Perhaps it is VA C++ (which I did not upgrade too).  

It is because of these types of problems that I do not let my code (or
myself) get tied to any one compiler/vender.
