I think the problem lies more within the PHP sqlite extension, if not sqlite itself - no PHP script should be able to crash the PHP interpreter like this.

We can see in the backtrace that Drush is attempting a totally legitimate SQL request - this should be failing:

Also - the backtrace seems weird to me, as it points to PHP 5.2.17 source code while the dependencies file you have included above says you are running 5.3.6 - can you explain this discrepency?

the mistake was mixed mariadb and mysql sources....
