It is something in the optimizer. As -O0 without this flag passes with flying colors as well.

Hrm... I have not looked through mysql code since 3.21.something. I think that I am going to ask the mysql folks if these options are actually right for mysql current. And if they remain right for 3.23. which is knocking at the door. Result will be posted to the list. But otherwise the way the patches are formulated right now if someone stays 100% within the package system there is nothing critical and everything works ;-) [snip] Cheers ;-)
