Description
# environment
- vim: VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Jan 7 2020 22:53:41)
- grepper.commit: 'dde6a66'
- OS:arch linux x86_64
- Mem: 8GB
- grepper configuration in vimrc:
Plug 'mhinz/vim-grepper' , { 'on': ['Grepper',
\ '(GrepperOperator)'] }
- other plugin:
# actual behavior
```bash
$ cd ~/.vim && vim vimrc
:GrepperAg :
```
# expected behavior
I want search all colon(:) in vimrc.
# bug
The terrible consequence of the above behavior is to cause a serious memory leak in just a few seconds, and finally the entire system must be reboot violently.
