[godot] Memory Corruption in Custom Skins about spine-runtimes HOT 6 CLOSED

To reproduce: add a button with this script on it to the mix and match example scene and press the button:

extends BaseButton

func _pressed():
	get_tree().reload_current_scene()

from spine-runtimes.

same bug i think:
#2202

from spine-runtimes.

same bug: #2185

from spine-runtimes.

Also crashes godot 4.1, ie: this https://spine-godot.s3.eu-central-1.amazonaws.com/4.1/4.1.3-stable/godot-editor-linux.zip

from spine-runtimes.

Note: using 'copy skin' instead of 'add skin' doesnt crash

What is the difference? Internal code looks almost identical except for the way mesh attachments are handled.

from spine-runtimes.

Sorry for this taking so long. Attachments use a reference counting mechanism so they an be shared between skin instances. There was a bug with respect to the handling of this system (part of spine-cpp) in spine-godot. This was quite hard to track down.

This should be fixed in the 4.2 branch now. Thanks for reporting.
