the code was attached,
I have set the windows system global environment variable 'XDEBUG_CONFIG':
XDEBUG_CONFIG="idekey=session_1".
The 'php-activescript.ini' is the config file like 'php.ini', the xdebug configuration is in it.
If not use xdebug, the 'project.exe' will running OK, if using xdebug, the 'project.exe' will crash with php_xdebug.dll

Visual Basic 6 code, use php-activescript:
build a project1.exe, then run the project1.exe
the 'php-activescript.ini' will active, and the php_xdebug.dll will be loaded, then xdebug will crash.

Private Sub Command1_Click()
ScriptControl1.Reset
ScriptControl1.Language = "PHPscript"
ScriptControl1.AddCode " $hello = 'Running OK!'; "
Label1.Caption = "Running OK"
End Sub
Private Sub ScriptControl1_Error()
Debug.Print ScriptControl1.Error.Description
End Sub

the 'debugclient.exe' could connected with the xdebug at starting, but any command will make the crash.(such as 'set_into -i 1')

[cmd]step_into -i 1

then xdebug Crash...
is it fragment fault ?

I have changed the PHP activeScript code to fix the bug.
everything goes OK.

What have you done to PHP activeScript to make it work?

cheers,

I don't know how i fixed the bug,
Xdebug crash on the PHPscript last branche 5.0RC4 or main trunk,
http://svn.php.net/viewvc/pecl/activescript/trunk/

but not crash on PHPscript branche 5.0 http://svn.php.net/viewvc/pecl/activescript/branches/PHP_5_0/
(many bugs, such as failing import object)

I merge the code about opcode compile and exectue, then bug fixed
---another important issue,
Exactly?Xdebug does not work on PHPscript any, even the crash bug above has been fixed.
PHPscript compile the code by 'zend_string_compile' function, but Xdebug only replace the 'zend_file_compile' function. So xdebug not rebuild the OPcode.
Little changes on the phpscript frag compile function(xdebug or phpscript), will fix this bug.

Closing this out, as I understand that the issue is no longer a problem.
