PHP Version: 5.0.0RC2
New Comment:
I experienced this crash on Linux 2.6.3 with PHP 4.3.3 and
PHP 5.1.0-dev snapshot 200407271430. Perhaps somebody
should set the category to "reproducible crash".
This is the PHP 5.1.0-dev backtrace:

I have the same problem, example :
<?
$somecode=1;
switch($somecode){
case 1:
function test(){
echo "success";
}
test();
break;
}
?>
With php5 final, this code was working with php 4.3.7
