This happens when I try to access a file on my webbserver that has a connection to mysql. The error appeaer after upgradering via swaret to
mysql-4.1.12-i486-1. How can I go back to the verison before to try?

You have problem with your packages upgrade...
What is the output with :

What do you mean by that?

Yes, I have had several problems with my packages upgrade. First my glibc was strange so i got back to 2.3.4 but now this remains.

What do you sugest that I do?

I would download the latest glibc package
(download not upgrade with swaret, just download)

Then I'd do a telinit 1 as root and upgradepkg glibc-xxx.tgz
After that, telinit 3 and upgrade coreutils package if newer
version is available

Hmm, Now i tryied to go back one verison of mysql to..and that worked. So no everything works. Best not touching anything.

I had the same glibc problem, this was 8 or 9 month ago
Now, I use glibc 2.3.5 and current slackware packages, all works fine

I understand you though...
the 'glibc detected *** double free or corruption' error is very frustrating..

Take some quiet time before the next upgrade

try
$export MALLOC_CHECK_=0

then run your appl. This will ignore the multi free() to particular memory.
