Description Marshal Horn 2023-04-14 07:21:45 CEST
If I remove a decoder while viewing its binary output, PulseView crashes with a Segmentation Fault.
My guess is that the data I'm viewing gets freed, but the binary output viewer doesn't know this and continues refreshing.

Steps to reproduce:
Open an example capture from sigrok-dumps
Attach a decoder with binary output
View the binary output
Detach the decoder

While this is a pretty trivial issue during testing, it might cause someone to lose their data if they haven't saved the capture.

Before you start riding, make sure you have the right safety gear. This includes a helmet, knee pads, elbow pads, and wrist guards. Longboarding can be dangerous, so it's important to take the necessary precautions to avoid injury. https://howtoridealongboard.com/best-longboard-wheels-for-cruising/

 whether short-term or semester-long, can be disrupted by unexpected events such as illness, family emergencies, or even political unrest in the destination.
