Description:
------------
Thank you for your quick attention to bug #16978

Unfortunately though it seems the modification made things worse - now you do not have to call the function to cause a crash.

Using constants as default parameter values in function definitions causes bcompiler to crash using  bcompiler_write_file.

I'm using php 5.3.1, bcompiler SVN. 

This does not occur in 0.6, not sure about 0.7 or 0.8 though


Reproduce code:
---------------
<?php
define("SOME_CONST",1);
function foo($var = SOME_CONST)
{ return;
}

?>


Expected result:
----------------
expect bcompiled code to run normally

Actual result:
--------------
crashes

Hmmm... I use the following test script to check my fix:
<?php
define("SOME_CONST",15);
function foo($var = SOME_CONST) { echo "var=$var\n"; }

foo();
?>
with expected output
var=15

It works on my PHP 5.3.2-dev (cli) built from the current SVN sources on Unix. But I will re-check it with a Win32 build.

I doesn't reproduce on Win32 with PHP 5.3.1 (cli) (built: Nov 19 2009 10:17:43). Let me send my .dll and bytecode file by e-mail - please test them.

recompiled and problem doesn't exist any more.
