Hello,

You must not initialize dbengine in the Initialization section and must 
not finalize it in that place (maybe only as last chance) because 
initialization order and finalization order is undefined by fpc and 
finalization of your code could happen after the whole DB structure has 
been finished, so the call to "DBLayer.Free" could try to free an object 
controlled by an engine which is not loaded yet.
