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)
