Completed a flight from KLAL to KMCO, upon turning of APU GEN got a CTD.

Upon reloading into airframe to try to continue shutdown of battery, same CTD, plane is not in a useable state for the moment.

Tried loading up on approach, 10 minutes before the CTD and I get a "wind sheer" alert after unpausing and then a CTD. Tried without any custom scenery or plugins, please see another set of logs attached.

Not sure if it helps pinpoint, but I loaded up a different airframe that I had, loaded up the battery, turned on apu and let it sit, then loaded up the APU GEN and then shut down APU Gen and APU without issues on that airframe.

Did a few more tests today and yesterday. 

1. Tried loading up the previous airframe, but this time not restoring trajectory, simply putting it at a new airport on the other side of the country, same crash as the previous logs.
2. Loaded up a separate airframe, did flight from KGLD KCBK VOFWE FEGIT KGLD doing the RNAV 30 approach. Parked, shutdown and all went without a hitch.

So at this point, I think something wacky is up with the airframe file possibly and the libc.6.so is having issues with it? Attached that airframe as it seems specific to it. Additional details:

OS: Arch based linux, custom distro.
Gnome: 41.3
Windowing System: X11
Graphics: Nvidia RTX 3070
Processor: AMD Ryzen 7 3700x 8-Core x16
RAM: 32 GB

Airframe is definitely borked. I will pass this on.

@oisin650 I may have recorded video of my shutdown as of that first crash. It may present nothing, but I can snip out down to the taxi to shutdown and upload if you think it'll help. I thought maybe it was something I did, but I did the same process this time and it worked. So please let me know!

That would be great, thank you. Please upload as either an MP4 or a YouTube link.

@oisin650 Please find attached the mp4 of the crash. I cut out cruise, descent and landing as those went as expected (minus a semi awkward landing in 34 knot gusting with 14knots of it being crosswind. I also cut out the stupidly long taxi I had to do due to poor planning on arrival runway (needed opposite side of Orlando). However, I show the post-landing checklist, engine shutdown and securing. It was on securing, I shut down the APU GEN, clicked the ISO and 10th Stage buttons, went to press packs and the CTD happened. Hopefully this helps! If you need other portions of the flight let me know! Do know, I didn't record take off nor climb, forgot to start OBS.. so only have cruise and onwards.
