Like the NTSB, I often wish the CSB had more teeth. 😑 They do a great job with their public communication it would be a massive loss to have them (further) defunded.

This UB was really surprising to me when I found out about it. Thank you for all the hard work you do for those of us who are still stuck using this language!

It has big disk energy.

The ARM/Keil and IAR toolchains both have a couple compression schemes they can use for .data on microcontrollers. It's been a while since I've used them, but I think they'll even exhaustively search the different compressors to find which is optimal on a per-section basis.
