And... if I'm not able to identify which part of the script do that ?
I don't know valgrind, is it possible to obtain some informations about
the partion of code which produce that ?
I suppose the name of the C functions should help to identify that, no ?
And zend_objects_store_del_ref is about object creation or destruction ?
And, it's an object created thought zim_PDOStatement_fetchObject ?
Thanks for any help.

Hello,
I have an other memory corruption problem ; I had the problem on PHP
5.2.6 on Debian Lenny (64bits), so I re-checked with the CVS version
(php5.2-200902060730).
When I run my (really huge) cli-script with valgrind, I obtain this :

I'm really not sure to can give a "test case" to reproduce the problem
; so, is this valgrind output suffisant ?
