Crash calling cmake configure: JavaScript heap out of memory

[cesar14]

Brief Issue Summary

The extension is always crashing whenever I run the cmake configure command. I was not able to reproduce this behavior in other projects, seems to be just happening in this project that i've been working on (the project has a very large code base). The crash is only happening in cmake versions greater than v3.21.2 with version v3.20.1 i was not able to reproduce the crash.

[riverwoodland]

I'm also having this same problem with cmake 3.21.2.

Does cmake work when you run the configure command outside of VS Code? If the differentiating factor is the version of CMake, it's possible that you would need Kitware to investigate this. You can open an issue for them here: https://gitlab.kitware.com/cmake/cmake/-/issues

[cesar14]

yes, outside VS Code cmake works as expected no error or crash occurs.
The crash is only happening in cmake-tools vscode extension.

[bobbrow]

Are you able to share a project that reproduces this problem? We have not encountered this before. I still think this should be on Kitware to fix so a report on their repo would be the best path forward, but we can try to help isolate the problem as well if you share some details as to how you are hitting the problem. Are you using a VM, or physical machine? How much memory?

[cesar14]

sorry but I can not share the details of the project. As I mentioned before the cmake commands are working as expected outside vscode.
I am using physical machine with 64gb of RAM. Is there a way to configure the extension memory? the crash seems to be happening when the extension is not able to allocate more memory which is very strange because accordingly to the logs the extension memory is near of 4gb (+/-10% of all memory available)

[Worrador]

Having the same problem. Any resolution?

[bobbrow]

I think this might be related to #970 and #2586. Do you happen to have a large compile_commands.json file in your cmake cache folder?
