gutentags make the /tmp directory run out of space in fedora 32

[zoumi]

When I startup gvim with gutentags enabled the space usage of /tmp grow rapidly.
I'm using Fedora32 64bit in VirtualBox.
I had set g:gutentags_cache_dir = expand('~/.cache/tags')

Gvim version:

VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Aug 31 2020 00:00:00)

If I remove this line from vimrc, the usage of /tmp doesn't grow.
let $GTAGSLABEL='pygments-parser'

[ludovicchabant]

What does $GTAGSLABEL do?

Can you identify the process that fills up the temp directory? (probably a gtags process?) This way you could look at its command line and figure out what it's doing.

@ludovicchabant
gtags will read environment var $GTAGSLABEL to call the correct parser.

For my situation, this problem only happens when I open vimrc in ~/.vim, then gtags will try to generate tags for all plugins under ~/.vim/plugged. So I tell gutentags ignore the path "~/.vim", it does not happen now.

I think it's a bug of gtags, so I will close this issue.
Thank you!

Ok thanks!
