[fpc-pascal] How are Assigned, Free, Nil and Destroy related?

[Ludo Brands]

When the loop runs again Assigned in InitVars is false so as soon as those
FBreakStrings and SCStrings are accessed within the loop a SIGSEGV occurs.
So what I want to know is whether Assigned  remains true when Free is
executed.

 

See my previous answer. 
 
There is a helper function "procedure FreeAndNil(var obj);" that calls
obj.free and sets obj to nil. So instead of SCStrings.Free; SCStrings:=nil;
call FreeAndNil(SCStrings);
