Which version of client library do you use?

No feedback was provided. The bug is being suspended because
we assume that you are no longer experiencing the problem.
If this is not the case and you are able to provide the
information that was requested earlier, please do so and
change the status of the bug back to "Open". Thank you.
 [2004-01-05 06:56 UTC] temnota at kmv dot ru 
Shared,  libmysqlclient.so.12.0.0
 [2004-01-05 08:07 UTC] georg@php.net 
This problem is fixed with actual MySQL Version  
4.0.17. You also have to compile PHP with 4.0.17 client  
libraries, not with bundled libmysql.  
  
If this will not work please reopen this bug.
