please review a fix for MDEV-5689.
It also fixes MDEV-5709 ExtractValue() with XPath variable references returns wrong result.
I pushed my patch to 10.0. But the reported test case did not crash without the fix. I guess this is because some fix was earlier merged from MySQL to MariaDB-5.5 and then to MariaDB-10.0.
Yes, I've merged the fix from MySQL-5.5
Should now a part of this MySQL fix be reverted in MariaDB-10.0?
As you like. If I recall correctly, it marks Item_nodesets as always not const. I don't see it causing any harm, these items are never part of the item tree, so their non-const-ness cannot be propagated up and affect other items and complex expression. But I could be missing something, sure. Regards, Sergei
