Tonight there was a power outage in my home where I have a RaspberryPi
4B development system with Lazarus 2.0.8 and Fpc 3.0.4.
When it happened the system was running including Lazarus.
Now when I start Lazarus I get to a dialog saying:

I've noticed some problem with another hashlist that after adding about
2000 items to it, it starts to have problems. There are duplicates added
(possibly a collision?)
Is there a such thing as a perfect hashlist which never has a collision,
or will they always have problems... In that case a
Since FPC has no associative array I was thinking that the closest is
TStringList with name/value pairs.
Then there is a hashlist in contnrs.
Maybe an associative array means you don't have to implement it using
hashes in order for it to work?
If there is a need for one I might write one as

No, there are infinite possible items you can add to a haslist, but
only a finite number of available hashes.
It's the pigeon hole principle:

BTW, sorry to be more clear I meant I used another hashlist unit, not
the contnrs one but another open source public domain one

Inside a generic procedure (no objects used just a procedure) is there a
way to check which type the code is being used for such as:
generic procedure Add();
begin
if type = integer then...
if type = string then...
begin
// specialized code for that type only
end
end;
I remember so

generic procedure Add;
begin
if TypeInfo(T) = TypeInfo(Integer) then WriteLn('an integer');
if TypeInfo(T) = TypeInfo(String) then WriteLn('a string');
end;
