Using the same project as in the bug report, almost every time I set the 
"Active" property of the SQLQuery1 component to true in the object 
inspector I get an "Access violation" and the selection tree in the 
object inspector gets messed up.
It doesn't happen if I use zeos.
I tried both with the original fcl-db and the one modified as my last 
message in the bug report (I rebuild lazarus every time I changed fcl-db).
Fpc 3.0.4/lazarus 1.8.2, win32 and linux (64 bits)/qt

The access violation happens inside 
TComponentTreeView.UpdateComponentsNodesValues, UpdateComponentNode, 
line "if APersistent is TComponent", when Anode is the first 
TSQLDBFieldDef in the sqlquery
