Freeze when running a specific code

[Thiago4532]

Every time I run the following code using ccls my computer starts freezing until ccls is killed. I did the test using nvim-lsp and vscode-ccls and both showed similar results.

Steps to reproduce:

1. Save the code to some file (I don't know if it's necessary, but the results looked worse if I saved the file before opening it).
2. Open the file using nvim-lsp. (I've tried to record the error but my KDE Plasma literally died when I opened the file.)

In Visual Studio Code I used a project that was already using ccls and pasted the code, and like NeoVim everything froze until ccls was killed.

The log from VSCode doesn't seem to have anything useful:

I don't know if this problem only occurs to me, so if you are able to reproduce it, please let me know.
