Hello!
I have a problem with newest stable version of gzdoom 4.2.1:

Warning: '==some object==' is freed outside the GC process.
Called from AltHud.Init at gzdoom.pk3:zscript/ui/statusbar/alt_hud.zs, line 74

Execution could not continue.

I have a version 3.6.0 - and i have no problems, but after update - i have this error.

P.S. GZDOOM without my mod work good even on 4.2.1, problem only if i want load my mod.

Sorry for my English...

Can you post your mod?

[yura_111]

No. Sorry. Mod very large, in alpha progress and therefore i can't post.

How can we fix it if we cannot reproduce it? Upload your mod somewhere and PM the link to GZDoom Developers.
Alternatively, you may try to create a small sample mod that has the same error.

No. Sorry. Mod very large, in alpha progress and therefore i can't post.

This literally makes it impossible to fix your issue. Sorry - but if you can't help us, we can't help you, it's not that we're looking for "super secret" shit, it's more to the point that if we don't have the materials required to create the issue ourselves, we cannot fix the issue. We're not superhuman, we're not mindreaders, and you need to understand that in most cases GZDoom works perfectly fine, the situation is pretty unique to your mod. It's as simple as that.

Sorry to give it to you bluntly like that, but it is what it is. Reality imposes limits on what we can do, and there's no way around it.

So if you want this issue fixed - give it to someone who can fix it. If you don't trust the entire GZDoom dev team, you can PM only _mental_ with it, instead.

Archive have a password, but i can't sent PM, because: " We are sorry, but you are not authorised to use this feature. You may have just registered here and may need to participate more to be able to use this feature. "

[Rachael]

Sorry about that. You should be able to send PM's, now.

Done it. Thanks!

The problem is with your super duper IWAD. It’s detected as Doom II, although it lacks small font lumps, STCFN*. Alternative HUD requires it, and that’s why it fails to start.
Additional warning is a side effect of the same failure during AltHud object construction.

... but in 3.6.0 - work good. If this my error - why work before 3.7.x ?

P.S. mod in alplha progress

Because over time, the engine gets fixed to prevent users from making critical errors like this. Like _mental_ says, the engine REQUIRES those fonts for the AltHUD at least. There's no negotiation there, never should have been. The fact that it "worked" before was probably missed by the devs in the past.

These kinds of things get fixed by the devs to prevent people from continuing to create bad data in their projects.

[Graf Zahl]

No, there is an actual regression here. The engine should fall back on the console font when the small font is not found.

[_mental_]

Like this?

[Graf Zahl]

Yes, this is precisely what was missed when the code got refactored.
