It's certainly not static in the C-meaning of the word. AFAIK it gets
reused when possible. Perl keeps mortal variables in the pad. When one
goes out of scope, I think it is not instantly free()ed but just marked
for re-use.
Under circumstances, this might lead to this effect of seemingly static
memory locations. But you cannot rely on that.
BTW: Have a look at perlclib.pod. There you'll find more libc
equivalents in the Perl API.
