People started reporting memory leaks when working with mysql (through
PDO, mysqli, mysql). I didn't try to investigate this issue, but i
assume the leaks may have taken place after andrey has switched zval
cache to off. You should take a look at this. See some bug reports after
andrey has posted about the change he has made to CVS.

The problem with turned zval cache off is away, but with turned on zval
cache bug still exists, so i assume the bug is NOT fixed, turning zval
cache off is a temporary fix, that's why i keep the bug open. Or i
shouldn't?

Do you still experience the problem? You said you don't or you see it
again? The zval cache is switched off and there is no way to enable it
without recompiling. If the problem persist we have to search for the
problem somewhere else.

I guess zval cache is not fixed on windows yet, so i open the bug.

Turning on is only possible through a recompilation. Maybe we can add
an ini option (INI_SYSTEM) to switch it without recompilation. But
currently the CVS is locked for changes.

Well, seems something is wrong with concurrent access to zval cache on
windows. Try turning zval cache on and test my code on windows machine.
