Apparently my crashes in a dll that use Firebird have to do with

Distilled reproducible code that demonstrates problem:
So, is there a way to do this, i.e., specify the 'root' director for your
units/includes and have it look at all files underneath regardless of
nesting level?
No, that's how -Fu is designed.

Hi!
I have a large project and it compiles under 32 bits cpu,
but doesn't under 64 bits. Here is a minimal problematic
part:
=
[doj@larion ~/temp]$ cat ptrtransform.pas
{$MODE OBJFPC}
const
C = -1;
var
A: array[0..1] of Pointer;

The code in question is:
initialization
DBLayer:=TDBInterface.Create;
finalization
DBLayer.Free;
... so probably initialization order plays a part?!?

What I would like to know what is the cause of this problem - dlls being
loaded before some kind - what kind? - of initialization is complete?
Anyway, I'll keep digging; probably first looking at geting postgresql
support in anyway.

You must not initialize dbengine in the Initialization section and must
not finalize it in that place (maybe only as last chance) because

IMO the problem is the transformation -1 into an unsigned value.
(Unsigned(-1) Max(Signed).)
How can I rewrite this code to make it correct? I want to use
constants to calculate offsets from untyped pointer.
have you tried using a typed const?

say for example:
type

procedure Something (sender : Tobject);virtual;
end;
var
myClass : TmyClass;
then somewhere
AddMethodToQueue(@myclass.Something);
Is it possible within AddMethodToQueue, I can query the Run Time Type
