I switch to another git branch, but gtags database didn't update automatically, so I tried to update manually. The first several times were susccesful, but then went wrong, showing gtags error, type :mess showed bellow. I deleted the gtags database, and tried the same procedure, and it happened again.

Steps to reproduce

0.gtags --version 6.6.10

1. cd to a repository,（ I git cloned uboot repository)
2. start vim, auto generate database successfully
3. exit vim
4. git checkout to another branch
5. start vim
6. type :Leaderf gtags --update (first time maybe success, by switch back former branch, try update gtags database again ,it will go wrong)

Actual behaviour

Leaderf gtags --update showing gtags error!

Expected behaviour

gatags database should update automatically after switch to another branch, and should not go wrong by update manually?

update: I found out each time I tried to update to gtags database by :Leaderf gtags --update, the size of gtags database will increased abnormaly, see below and :mess, first time went error actually showed malloc(): corrupted top size,

And I could reproduce it by just type gtags -i --skip-symlink --gtagslabel native-pygments in terminal. But by removing the param -i will runs fine. I looked up the help file of gtags, -i stands for increased, still not know why.

I don't know either. Maybe it's gtags' bug.
