This is a well-known, bogus warning in older versions of g++. 
Unfortunately I don't have access to the version that produces
this warning so I couldn't test my work-arounds (g++ 3.3.6 as 
well as 3.2.3 that I have access to don't have this bug). 

I think the following should work (besides upgrading the compiler,
of course):

functionTakingAnInt((int&)stock.get_id ());

const ReferenceDataId& id (stock.get_id ());
functionTakingAnInt(id);

Making stock const should also help. If you don't plan to modify
stock then this might be the cleanest approach.
