The specific ls-files call that seems to trigger the segfault on Magit's end is equivalent to cd .git && git ls-files --error-unmatch -- $PWD/COMMIT_EDITMSG The code is running ls-files to ask whether the file is tracked, which of course isn't a sensible thing to do outside of the working tree. I'll propose a change on Magit's end to avoid doing so. [ A few more specifics that might be of interest to Magit users ] This happens in magit-auto-revert-mode. When visiting a file in .git/ (e.g., COMMIT_EDITMSG when committing), magit-auto-revert-mode decides whether to turn on auto-revert-mode in the same way it does for other files, magit-turn-on-auto-revert-mode-if-desired. That function doesn't distinguish whether the file is in .git or the working tree, leading to the odd "is tracked file?" query above.
