[Lazarus] Lazarus crashing reproducibly on startup (64-bit Linux)

[brian]

I've recently switched distros to Mint Debian 12 64-bit XFCE. This is 
on an AMD Phenom *4, 4 GB of RAM. When I was reinstalling stuff I 
noticed that the latest version of Lazarus that they have in the repo 
is 0.9.28, a bit old I know, but it works for what I do.

So I installed 0.9.28, which also brought in FPC 2.4.0-2.

When I try to run Lazarus from the menus, I get the splash screen and 
then nothing, the IDE never comes up.

So, I switched to a terminal, ran startlazarus and got the following 
output.

[WARNING] Out of OEM specific VK codes, changing to unassigned
[WARNING] Out of unassigned VK codes, assigning $FF
TLazarusManager.Run starting /usr/lib/lazarus/0.9.28.2/lazarus ...
Runtime error 203 at $0000000000736A16
   $0000000000736A16
   $0000000000720991


OK, maybe it's an old version. I downloaded the latest .DEBs from 
SourceForge, and installed those. No change in the symptoms (well, OK, 
I can't say the addresses were exactly the same, but the bit about the 
VK codes was, and it was still a runtime error 203).

I cleaned out everything to do with Lazarus and FPC that I could find 
(using KFind to make sure I got everything) and had one more try with 
0.9.28. As expected, still the same error. I know that 0.9.28 used to 
run on Mint 9 64-bit, but that was the Ubuntu-based version, not the 
Debian-based one.

Anyone have any ideas how to fix this, please?
