[PHP-DEV] Bug #12620 Updated: PHP.exe is causing access violations when shutting down
ID: 12620
Updated by: [EMAIL PROTECTED]
Reported By: [EMAIL PROTECTED]
Status: Bogus
Bug Type: Reproducible crash
Operating System: Windows NT 4 Server
PHP Version: 4.0.6

PHP is still crashing in shutdown_memory_manager() although I've now
found that if I compile PHP with ZEND_DISABLE_MEMORY_CACHE set to 1,
the problems don't occur.
I'm still unable to provide a short section of code that reproduces the
problem as doing something as simple as adding
echo hello;
to a page that crashes can stop it from crashing.
If I remove a function that isn't even called it can sometimes stop
crashing, other times it continues to crash no matter what you change,
it seems quite random but if a page crashes it does it consistently.
It's just that changing them in the slightest way can seem to alter the
behaviour significantly
Does anyone know anything that might cause the memory manager to fail
like this, or even if compiling PHP with ZEND_DISABLE_MEMORY_CACHE 1 is
a reasonable thing to do?

I've been using the v4.06 windows binaries from this site and have been
suffering repeated crashes as PHP closes down.
The crash is either reported as just in PHP and other times
OLEMainThreadWndName is reported in the error. It varies between write
and read violations too.
I've traced through the code and have tracked it down to an access
violation in the function shutdown_memory_manager().
Also when using the win32 debug build of PHP the error does not occur,
only with the release version.
The app I'm working on has database connections and uses COM objects.
The error seems to be slightly related to the database side although
I've not been able to produce a small section of code that causes the
same error. I'm using the ADODB wrapper for database access although
the same error has occurred when using the built-in ODBC functions.
I can't see that I'm doing anything wrong but there's definitely
something that PHP isn't liking.
Below is the main function I use to get results from a database, when
all the code is commented out inside this function the error doesn't
occur but a lot of other stuff in the app doesn't happen either so that
doesn't say much really. Is there anything blatantly wrong with the
code below?
function GetDirectoryQueryResults($szSQL)
{
$objConn = ADONewConnection('ado');
$objConn-Connect(Directory);
$objRS = $objConn-Execute($szSQL);
if (!$objRS-EOF)
$retval = $objRS-GetRows();
$objRS-Close();
$objConn-Close();
return $retval;
}
Cheers!

The version of PHP that this bug was reported in is too old. Please
try to reproduce this bug in the latest version of PHP (available
