• other plugin:

actual behavior

$ cd ~/.vim && vim vimrc

:GrepperAg :<CR>

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.

Same issue here, not only with colon, but search some words, a letter, causes freezes/neovim to crash or event the whole OS to crash

Neovim 0.9 Latest vim-grepper Mac M2 OSx Ventura

Tested with a vimrc that has only vim-plug + vim-grepper to avoid any issue caused by other plugins, and problem remains.

Not sure what to do about this.
