Hi
Sometimes using gutentags with gtags will generate empty GTAGS, GPATH,
GRTAGS. I and others come across this question.
Look https://github.com/ludovicchabant/vim-gutentags/issues/225 for
detailed background. I tried many ways mentioned in the link but cannot
solve the problem.

How can we solve this? I guess some unsupported files may corrupt gtags
files.

Appreciate your help.
