Description:
------------
When nesting a class within another class function, PHP crashes.
I have PHP running on an Apache2 (2.0.47) server as a module.
Changes in my php.ini, different from php.ini-dist are my SMTP server setting, my error reporting level setting to E_ALL and the floating point number precision to 14. No exentions are enabled.

Reproduce code:
---------------
class foo {
 function bar() {
  //here comes the line of doom:
  class my_class {}
 }
}


Expected result:
----------------
I expected PHP to return a fatal error which says that classes cannot be nested.

Actual result:
--------------
PHP crashed...
I am using Windows, so I have not got a backtrace. I have sent an error report to Microsoft; maybe that helps.

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
