Hi Zeev;
Seems to have fixed the problem. What is this expected to be included
in a final version 4.0.7 I assume... I try to avoid alpha/beta but I
suppose I have little choice at this time. Now I just see enormous amounts
of:
string.c(1341) : Freeing 0x086AB454 (6 bytes), script=/path/to/scripts
I assume that's normal in debug mode for the Zend cleanup engines... So
I suppose all is well. Thank you so much. If you have a guestimate on the
next release including all of this, that would be amaizing.
Thanks for all of your help;
