Hi,
x64 Suse 11.1, the program:
"
program gdbvarparam;
{$ifdef FPC}{$mode objfpc}{$h+}{$endif}
{$ifdef mswindows}{$apptype console}{$endif}
uses
sysutils;
procedure test(var par1: integer);
begin
end;
var
int1: integer;
begin
int1:= 123;
test(int1);
end.
"
The debug session:

Why is it not possible to set a breakpoint to "test"?
Is it as designed that the displayed value of a var parameter is the address
instead the value?
