Although it may not be apparent from the test case I provided, there IS a bug here. 
 
The intent of the constructor is to zero the smart pointer.  If I step through my 
production code with GDB, I see that the pointer is not zeroed.  Furthermore, code that 
depends on it being zero breaks. 
 
The constructor code shown stores a zero into the pointer address pushed onto the stack.  
As the code currently is generated, this will have the effect of CLOBBERING some random 
memory location.  I have confirmed this in GDB. 
 
I am reluctant to upload the full source code base as it is part of a commercial project. 
 
I will attach a log from GDB showing how the location addressed by the previous contents 
of the variable gets clobbered.
