Pattern not found in C/C++ files even with a ctags file.
- It used to work and I haven't made any configuration/plugin changes that I know of
- Starting vim with
vim -u NONE -U NONEand manually setting
omnifunc=ccomplete#Completeresults in the same problem (as does
vim --clean), so it doesn't seem to be caused by my vim config
- Python and HTML omnicomplete still works, so the problem seems to be with the tags file
<C-x><C-]>still work and complain when the tags file is removed, so the tags file seems to be fine??
- I'm using Gutentags with Universal-Ctags in Vim 8.2 to automatically generate the tags file (tried a stock Neovim config as well and still the same error)
Any ideas what the problem could be or how I could go about debugging it?
