I tried running the segfaulting nvim again, but with the TERM variable unset. It does not segfault. TERM= /gnu/store/d8ibld5vpsgq7is3k3sf5gqj0i7sgmbh-neovim-0.3.4/bin/nvim Any other value for TERM that I tried leads to a lookup of the terminfo files provided by the ncurses package and subsequently leads to a segfault. I would also like to point out that this does not segfault: guix environment --container --ad-hoc neovim -- nvim Outside of the container ~/.guix-profile/share/terminfo is available, which resides in my profile because I happen to have rxvt-unicode installed. This package provides these files: ./share/terminfo/r/rxvt-unicode/rxvt-unicode{,-256color} The value of TERM in my sessions is “xterm-256color”. -- Ricardo
