Using scons in release, crash when initializing gdextension.

[whileload]

Godot version

4.5

godot-cpp version

4.5

System information

Windows 10

Issue description

I used two compilers: msvc and llvm.
Build via CMake works.

Possibly related.

Steps to reproduce

scons platform=windows target=template_release

Even with an empty extension, where there is only an initialization function.

using namespace godot;

void initialize_gdextension_types(ModuleInitializationLevel p_level) {
	if (p_level != MODULE_INITIALIZATION_LEVEL_SCENE) {
		return;
	}

}

void uninitialize_gdextension_types(ModuleInitializationLevel p_level) {
	if (p_level != MODULE_INITIALIZATION_LEVEL_SCENE) {
		return;
	}
}

extern "C" {
// Initialization
GDExtensionBool GDE_EXPORT
resouls_library_init(GDExtensionInterfaceGetProcAddress p_get_proc_address,
		GDExtensionClassLibraryPtr p_library,
		GDExtensionInitialization *r_initialization) {
	GDExtensionBinding::InitObject init_obj(p_get_proc_address, p_library,
			r_initialization);
	init_obj.register_initializer(initialize_gdextension_types);
	init_obj.register_terminator(uninitialize_gdextension_types);
	init_obj.set_minimum_library_initialization_level(
			MODULE_INITIALIZATION_LEVEL_SCENE);

	// There is a crash in this function. 
	GDExtensionBool r = init_obj.init();


	return r;
}
}

Thanks for the report!

When it crashes, I assume you're loading the GDExtension in a release build of Godot? Or, are you loading the release GDExtension in a debug version of Godot (like the editor)?

There are some known issues with mixing release and debug builds in Godot 4.5 and earlier, and it's recommended to only use release GDExtensions with release Godot, and debug GDExtensions with debug Godot.

Anyway, just wanted to quickly confirm if that was your issue, or something else

Build via CMake works.

Makes me wish I finished automating my build flag comparison tool. @dsnopek if you think it worth while I can do some fresh analysis of the builds to make sure they're still in sync in terms of compile commands.

Sure, I think it would be worth checking! We don't test building with LLVM on Windows all that much, so I also wouldn't be surprised if our scons configuration does something weird in that case, although, the reporter says the issue happens with MSVC too

@dsnopek there's still some cleaning to perform but this might help, I havent analysed the contents, I've just been playing around generating the thing from compile commands:

I've updated that link , should be more fun to look at now.

[enetheru]

can you share the build commands you use to build using cmake please?

[enetheru]

I've tested and could not replicate a crash.

• Win11
• both msvc, and clang-cl from visual studio 2022
• using scons
• integration testing project, and stripped down version copy and pasted from above.
• official 4.5 editor, release and debug templates.

Granted I'm on Windows 11, so i dunno.

Dude...
Thanks for reporting this!
