System information

Arch Linux on Wayland - Wayland display driver, Multi-window, 2 monitors - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3060 Laptop GPU - 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz (16 threads)

Issue description

I discovered this issue while working on Godot 4.5 support in sentry-godot GDExtension.

When callstack tracking is enabled in release exports via debug/settings/gdscript/always_track_call_stacks, exported builds can crash on exit. With a GCC build on Linux (target=template_release debug_symbols=yes), I get SIGABRT and this printed:

double free or corruption (!prev)

Callstack state:

Likely related to:

• Static Initialization Order Fiasco bugs reported by Coverity Scan #106235

Steps to reproduce

Enable debug/settings/gdscript/always_track_call_stacks in the project settings. I wasn't able to reproduce it on an empty project. You can try with a sample or a production project. It crashed with several different projects, but not with a minimal setup, for some reason. This also happens on macOS. Didn't test on Windows.

Minimal reproduction project (MRP)

Don't have one at the moment. I'll see if I can reproduce in some public demo project.
