Re: [PHP-DEV] PHP 4.0 Bug #7720 Updated: Return address instackoverwritten? From: Adam Wright (adam <email protected>)

Only *nix systems have dynamic stacks, windows based programs live with a
fixed size stack setup at compile time (last time I did win coding, anyway
:). There are many other ways of dealing
with a recursive situation that won't involved you running out. Either way,
to far OT now for my tastes. Its not a real 'bug', live with it.
