I use dynamic arrays for data structures and sometimes types.

Under linux I have had no problems with transversing the list of data and calling "Done" on all types then calling finalize on the list itself.

Under windows I just executed the same code that worked under linux but crashed under windows.

TInt64Array=Array of Int64;
procedure Done(var List:TInt64Array);
begin
  Finalize(List);
end;
procedure Empty(var List:TInt64Array);
begin
  SetLength(List,0);
end;

In the above case the two procedures worked under linux. Under Windows Done crashes. Is this a bug that needs to be reported or is the memory manager performing different under Linux than under Windows.

This is a basic example. Some of my data structures involve strings and sub-arrays to other data structures or pointers thereto. To fix the problem I just use Empty instead of Done but I am looking to find out why can use Finalize on Linux but not on Windows?

Why do you want to finalize it ? This is automatically done by fpc when you set the length to 0 (or when the array goes out of scope)

Both should work and have the same effect, afaik. So please report a bug.
