That *only* applies to register variables, not stack variables. We very very much want to preserve scope of stack variables, because we very very much want to share stack space between stack variables of different scopes. Failure to do so causes bad interactions with inlining, and causes stack space consumtion to grow to unacceptable levels. I.e. you can't build kernels anymore. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32327
