Summary: More than 20 parameters functions make xdebug crashes
Description:
-------------- Script 1 ----------------
<?
   function a()
   {
      return true ;
   }

   a( 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
      11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21 ) ;

   echo "This message won't be printed\n" ;
?>

No apache response :
[mathieu[@]localhost test]$ netcat 192.168.0.4 80
GET http://192.168.0.4/ubi/test.php
[mathieu[@]localhost test]$

-------------- Script 2 ----------------

<?
   function a()
   {
      return true ;
   }

   a( 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
      11, 12, 13, 14, 15, 16, 17, 18, 19, 20 ) ;

   echo "This message will be printed\n" ;
?>

Apache output :
[mathieu[@]localhost test]$ netcat 192.168.0.4 80
GET http://192.168.0.4/ubi/test.php
This message will be printed
[mathieu[@]localhost test]$

Both of these tests work well when xdebug is not activated in php.ini. It
makes me think you allocate statically something with a 20 value. Or you
talked about a limit and I didn't see it.

Hope it can help you

There is indeed a static limit of 20 in Xdebug 1.3, and a limit of 32 in
Xdebug 2.0. I will definitely fix this in 2.0, but not sure about 1.3 yet
as there might be too many different things to be done and I don't really
want to re-do it for 1.3. If you can compile Xdebug yourself, just change
the "20" in line 156 of php_xdebug.h to something higher and recompile.
