from http://gcc.gnu.org/onlinedocs/gcc/Labels-as-Values.html:

"You may not use this mechanism to jump to code in a different function. If 
you do that, totally unpredictable things will happen. The best way to 
avoid this is to store the label address only in automatic variables and 
never pass it as an argument."
