[Lazarus] Can't find unit contnrs used by Masks

[Michael Schnell]

Hi Hans Peter and other Experts,

As I wrote some days ago, after, with your kind help, being able to 
rebuild Lazarus, I get a "SIGSEGV"error when creating a new empty 
project and starting it.

After some testing I found that I can run a new empty gtk2 project (even 
after adding some controls and functionality) when I set 
Project->Options->Linking->Link Style: "Link Smart".

Is this setting supposed to be correct  or "normal" ?

Is this setting supposed to be default with a new gtk2 project ? If yes, 
why is it not set with my installation and where can I change this ?

Is it normal that non-smart-Linking does not result in a working project ?

Thanks a lot,
-Michael
