Summary: Crashes in PHP-CLI and PHP-Apache
Description:
as I already stated on php.pecl.dev,
PHP-CLI and PHP-Apache crash out with Xdebug2 installed, although it works
okay with PHP-CGI.

Apache -- the last 1.3.x version
PHP -- 5.1.x-dev last snapshot
XDebug -- 2.x last snapshot

negative.
i'm still having crashes.

PHP-bin: latest snapshost (Built On: Nov 04, 2004 19:30 GMT)
PHP-src: current CVS
xdebug-src: current CVS (binary built with MSVS.NET)

starting PHP-CLI:

Then I really need more information, as it works fine on Linux for me (and
i can't test on Windows). Perhaps you can try the latest snapshots of both
PHP 5.1 and Xdebug one more time?

PHP 5.1.0-dev (cli) (built: Jan 29 2005 08:28:31)
both php_xdebug.dll downloaded from snaps.php.net and built from CVS:

php.exe crashes after a script is finished executing.
php-win.exe crashes.
php-cgi.exe doesn't crash at all.

I suppose I have to try it with the latest snapshot, but neither of two
today's snapshots were able to run on my box without crashes.

Either something's wrong with my box (although I doubt about that, since
my currently installed snapshot works well), or there are some bugs in
PHP5.1 snapshots and we have to wait untill they fix them.

I think we should ask someone else who got WinXP installed to test the
module.

I get the same problem under php 5.0 and apache 2.

Run TestMain.php to repo the problem.

---- TestMain.php -----
<?php

require_once 'TestClasses.php';

$silly = new SillyClass();

$silly->sayHi();

try
{
    $silly->explode();
}
catch(MyException $e)
{
    echo "Caught MyException " . $e;
}

?>

------ TestClasses.php -------
<?php

class MyException extends Exception
{
    public function
    __toString()
    {
       return __CLASS__ . " My Exception";
    }
}

class SillyClass
{
    public function
    sayHi()
    {
        echo "<p>Hello World</p>";
    }
    
    public function
    explode()
    {
        throw new MyException();
    }
}

?>

I should note that this is under Windows (using Komoto).

Exceptions are definitely the cause.

Confirmed using latest PHP 5.1 and Xdebug snapshots. Can't debug here but
will try to get some more information.

No crash using PHP 5.0.3 (as released) and Xdebug snapshot.

----------------------------------------------------------------------
 derick - 2005-03-10 22:14 CET
----------------------------------------------------------------------
Should be fixed in CVS now - please reopen if problems keep occuring, but
provide a sample script then.

Still getting crashes with the latest PHP-5.1 snapshot (Built On: Mar 15,
2005 19:30 GMT) and XDebug-2.0.0beta3-dev.

I've tried that with:
- DLL from snaps.php.net
- DLL from xdebug.org
- DLL, compiled here with MS VS .NET 2005 out of CVS-HEAD source

Also tried to play with options in my php.ini file with no result.

I suppose, the crash appears in RSHUTDOWN or MSHUTDOWN functions, because
everything's executed OK, and when PHP is being terminated, it segfaults
with a common Windows crash-dialog.

This is applied to only php-cli and php-win interfaces.
php-cgi works OK.

Am I the only one who has the bug?
Can anyone else confirm it?
What can I do to provide you with more information?
