Description:
------------
When you activate the mySQL Extension on Vista, PHP is delayed for about 3-4 seconds after every script execution.
As far as I found out this happens when PHP finalizes (so something like a destructor or so).
Problem can be reproduced.

Even if NO mySQL related code is called!!!


I am using a CLI version of PHP 5.2.6. The problem can also be reproduced when you use SAPI to embed PHP in you own application.

I did not test that with IIS/Apache or any other webserver.

Reproduce code:
---------------
//Any code will do
echo "Hello World";

//This takes about 5 secs to execute on Vista with mySQL Extensions on.

Expected result:
----------------
Either a delay only when something mySQL related is used (eg: mysql_connect) or no noticable delay at all.



Actual result:
--------------
Every script is delayed 5 seconds.

Sorry, but what info are you missing?
I read the "how to post bugs" page, but I do not see what I am missing.

Thank you,
Bernhard

I assume this is from the "Error in my_thread_global_end(): 1 threads didn't exit" thing: see Bug #41350, or Google... I had noticed it in CLI (but not Apache module), but hadn't looked into it since I thought maybe I had messed something up with different PHP builds, etc., but it definitely looks like it's still a widespread issue?

Hello!

Okay, sorry. It seems to be the same bug. You are right.
But I realy searched for the bug before posting. I looked at "Vista" and "MySQL" related bugs and didn't find that.

Also, I do not get an error message - I just get this delay.

Anyhow. I will close the bug, since bug Bug #41350 is still open.

Sorry for wasting your time,
Bernhard
