VS Code Crashes Daily

[jvilk-stripe]

• VS Code Version: 1.53.2 (N.B.: We cannot upgrade to 1.54 or insiders due to this issue which breaks many of our core extensions: VSCode 1.54.1 breaks spawned processes with cwd option #118267)
• OS Version: macOS Catalina

Steps to Reproduce:

One engineer at my company experiences VS Code crashes 1-2 times per day. There is no apparent pattern, and no others have reported this issue. They have captured a crash dump.

Here is the crash dump in a zip file.

Let me know if you require any additional information. Also, if there's a way that I could receive a symbolized version of the crash dump... that would be swell. :)

Does this issue occur when all extensions are disabled?: Using VS Code without extensions for a full day would be a pretty big regression in productivity. I can ask them to do this, but I suspect the crash report will be useful even without this data point.

Code crashed due to out-of-memory, I can't say if this is from an extension or the app with above data. As next step, lets take a memory profile of the workbench.

• Toggle developer tools
• Go to Memory tab and select Allocation Sampling
• Let it run for a while
• In the System activity monitor, check for the memory growth so that you can terminate the above profile before the process crashes.
