The previously released (RC) version 0.4 was found to be working w/o
known bugs with the latest stable FPC 2.6.0 (svn revison 19845). Now
virtually (re)releasing the previous RC1 as the offical" stable.

Hi list,
after a long pause I'm trying to revive some code which I didn't touch
as long as early this year. At that time it compiled OK with trunk FPC
(I believe version 2.5.1). Now I'm trying to make that code work with
current stable (AFAICS that's 2.4.4). Everything went smooth until

AFAIK exactly that is the problem and that's why TFPGMap can't cope
with some types.

I guess: In the callback you have to get the current window id using
glutGetWindow, then dispatch the call to the right object instance
using that id via some kind of mapping from wind

A bug may show anytime anywhere, but the built in ref counted string

Hi Juha,
I just tried and can confirm that a LCL app running inside Lazarus

show the place of an range check error (Ubuntu 10.04/AMD64). What I've
not tried, but suggest to try, is to open the

IMO just cast it to the correct type (of the array index) giving the
compiler a chance to accept it.

Hi all,
I tried to specialize fgl.TFPGList with some record type and got a

Am I doing something completely wrong (sorry in that case) or is this
a bug? (Ubuntu 9.10, 64 bit)
