[Bug]: Reprodcible SIGSEGV when closing obs-studio
What happened?
Every time I close the app, I get a SIGSEGV,
#0 0x000073a026f77c5b in srt::sync::CThreadError::ThreadSpecKeyDestroy (e=0x581cb953c220) at /usr/src/srt-1.5.3-1build2/srtcore/sync_posix.cpp:536

What should have happened?
The app should have closed gracefully, no seggies.
It's mysterious to me currently why that's happening in the snap, but not the Flatpak. The obs binary in both environments dynamically depends on the same version of the libsrt-gnutls version (1.5.3), yet the global destruction sequence is somehow crashing in Snap, but not Flatpak.

OBS Studio is software designed for capturing, compositing, encoding, recording, and streaming
video content, efficiently.
**NOTE: This is a community-supported modified build of OBS Studio; please file issues on the
Snapcrafters GitHub: https://github.com/snapcrafters/obs-studio/issues**
**Batteries included**
The snap of OBS studio comes pre-loaded with some extra features:
* Supports **nvenc (NVIDIA) and VA-API (AMD & Intel) accelerated video encoding**.
* **Advanced Scene Switcher** plugin; an automated scene switcher
* **Browser** plugin; CEF-based OBS Studio browser plugin
* **Directory Watch Media** plugin; filter you can add to a media source to load the oldest or
newest file in a directory.
* **Dynamic Delay** plugin; filter for dynamic delaying a video source.
* **Freeze Filter** plugin; freeze a source using a filter.
* **GStreamer** plugins; feed GStreamer launch pipelines into OBS Studio and use GStreamer
encoder elements.
* **Move Transition** plugin; move sources to a new position during a scene transition.
* **NDI** plugin; Network A/V via NewTek's NDI.
* **RGB Levels** plugin; simple filter to adjust RGB levels.
* **Source Switcher** plugin; to switch between a list of sources.
* **StreamFX** plugin; collection modern effects filters and transitions.
* **Text Pango** plugin; Provides a text source rendered using Pango with multi-language
support, emoji support, vertical rendering and RTL support.
* **Transition Matrix** plugin; customize Any -> One or One -> One scene transitions.
* **Waveform** plugin; audio visualization using fftw.
* **Websockets** plugin; remote-control OBS Studio through WebSockets.
**Connecting Interfaces**
For the best experience, you'll want to connect the following interfaces.
sudo snap connect obs-studio:alsa
sudo snap connect obs-studio:audio-record
sudo snap connect obs-studio:avahi-control
sudo snap connect obs-studio:camera
sudo snap connect obs-studio:jack1
sudo snap connect obs-studio:kernel-module-observe
**NDI**
If you want to use the NDI plugin you'll need to connect the Avahi Control interface.
snap connect obs-studio:avahi-control
**Virtual Camera**
Starting with OBS 26.1.0, Virtual Camera support is integrated. Here's how to install and
configure `v4l2loopback`:
sudo snap connect obs-studio:kernel-module-observe
sudo apt -y install v4l2loopback-dkms v4l2loopback-utils
echo "options v4l2loopback devices=1 video_nr=13 card_label='OBS Virtual Camera'
exclusive_caps=1" | sudo tee /etc/modprobe.d/v4l2loopback.conf
echo "v4l2loopback" | sudo tee /etc/modules-load.d/v4l2loopback.conf
sudo modprobe -r v4l2loopback
sudo modprobe v4l2loopback devices=1 video_nr=13 card_label='OBS Virtual Camera'
exclusive_caps=1
**NOTE!** Using `video_nr` greater than 64 will not work.
**Removable Storage**
To access content on external storage, connect to the removable-media plug:
snap connect obs-studio:removable-media
**3rd Party plugins**
To install pre-compiled plugins, download and extract the plugin to
`~/snap/obs-studio/current/.config/obs-studio/plugins/`.
This is how the Input Overlay plugin looks when correctly installed:
/home/username/snap/obs-studio/current/.config/obs-studio/plugins/
└── input-overlay
├── bin
│ └── 64bit
│ └── input-overlay.so
└── data
└── locale
├── de-DE.ini
├── en-US.ini
└── ru-RU.ini
If you want to use the Input Overlay plugin, you'll also need to connect the joystick interface:
snap connect obs-studio:joystick
