A program just crashed on me with a segmentation fault. That reminds me of the "Not planned" closed bug from 2023 in makepkg. makepkg crashes (at least back then) when given an extremely large PKGBUILD as an argument.

(As far as I can tell, it's not particularly catastrophic - just a poor user experience due to a vague error message)
