Do I understand correctly that it crashes when you try to open
Project->"Create Project ..." or "File"->"Create ..." dialog?
Yes.
It works just fine here with FPC 3.2.2 (in Xfce, but I doubt that it
matters in this case). Are you using FPC 3.3.1?
No, I only use FPC 3.2.2 to compile Lazarus, never 3.3.1.
I am not so sure that it is not related to Xfce, I suppose it uses a
different window manager than Linux Mint ? I had problems with Lazarus and
Cinnamon in the
past: more often than not starting a debugging session crashed Cinnamon.
But that improved when I upgraded to Mint 21. Maybe it is a regression in
Cinnamon, but since Lazarus is the only program on my computer that has this
issue, I tend to look at Lazarus for the cause.
My main problem is that I have no clue how to debug it, maybe the --sync
option as explained in the error message will tell me more.
Well, I am now 99.99% sure it is a Lazarus issue, recently introduced:
It also happens on my work PC: a standard Ubuntu 22.04 with Gnome.
I didn't have it before. Only after updating lazarus to the latest git
wednesday.
Unfortunately, I don't have the exact git commits :/
However, now I have a backtrace when running with --sync:
