This code is undefined
Take a look at the manual:
http://gcc.gnu.org/onlinedocs/gcc-4.1.2/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.
There is nothing special about this code, except it is undefined :).
