I don't have specifics, but rumors say industrial quantities have "gone  
through walls" and even killed people.

As you say the danger is probably a runaway reaction with the container  
failing or spilling over due to many bubbles and the creation of HCl and  
chlorine fumes. Remember HCl boils at only like 50C or so. Also, gaseous  
chlorine is sometimes used for industrial regeneration which adds danger  
too.
