cpptools crash - `The language server crashed. Restarting...`

[Colengms]

We're very interested in fixing crashes. Information that could help us fix crashes include:

• Crash stacks.
• Specific guidance on how to repro a crash.
• Isolated examples that reproduce a crash and can be shared with us directly.

If you're experiencing a crash, any of the above information could be extremely useful to us to investigate and fix it. Please consider opening a new issue in this repo. Or, add a comment on this issue.

I'm pinning this issue, to make this more obvious to users who might be browsing our repo due to experiencing a crash.

Just to remind that on macOS: #9810

@H-G-Hristov Yes, but that issue mentions a work around via running lldb -p <processId>, then continue (assume it gets into a stopped state), and then repro the crash, and use bt to get the full stack of the crashing thread (maybe bt all if bt isn't sufficient for some reason).

[sean-mcmanus]

I've reproed multiple crashes. I'm tracking it with #10636 .

We may not need this issue anymore.

Reopening. The intent of this issue was to be pinned so users experiencing a crash can find the issue and easily find instructions. I'd like to keep this open and pinned for now.
