RangeError: WebAssembly.Instance(): Out of memory: Cannot allocate Wasm memory for new instance
Type: Bug
Install C/C++ and Modern Fortran Start remote ssh in VsCode and check "Extension Hoste (Remote)" There is enough space in the directories to expand / save files up to 20 GB that should not be the problem.

@mdeberts Does this bug repro with the Modern Fortran extension disabled?
@mdeberts Does this bug repro with the Modern Fortran extension disabled?
I don't install Modern Fortran and also see this error on my remote server. When I reinstall 1.20.5 no error occurs.
Hi @mdeberts . Since this isn't happening for most people, can you tell us more about your remote machine? Is there anything about how it's configured that may be non-standard or different from default?
Between those versions, we upgraded several of our dependencies (for security purposes), including webpack, which appears to be where this issue is coming from (before any of our code actually executes).
@Thomasyse @Colengms I also tried a reinstall of 1.20.5 and now it works. The remote machine is a high performance computer (hpc). I connect to the login node via remote ssh from my linux workstation.

I uninstalled Modern Fortran and opened a .cpp file.

Same error, similar setup (but while trying to solve it, I've mode the vscode cache folder to a custom location outside my tiny home directory which has a limitation of 4 GB), no Fortran extension (just tried plain C/C++ project in the remote ssh project). Downgrading (from 1.21.4) to 1.20.5 worked.
Note: without remote ssh, everything worked on my Windows host.
I suspect the issue has something to do with:

https://github.com/webpack/webpack/issues/15584#issuecomment-1146566931
@mdeberts , @Thomasyse , @kvoronin , Can you confirm whether or not you have a memory limit set, and whether unsetting or increasing it avoids this memory allocation issue in NodeJS?

I set the Max TS Sever Memory to 4096. It seems not a concern?
Update This are my updated ulimits, I can not increase ulimit -v any further by myself. I also updated to 1.21.5 but still I get the same error.
I updated to 1.21.6, and it works again if I use my remote ssh from a linux machine.
But I still get an WebAssembly error, which does not seem to have a negative effect for now. All extensions but C/C++ disabled.

updated my upper post, since somehow connecting via remote shh from my windows machine it is not working, but if I connect via remote ssh from my linux machine it works.
@mdeberts @Thomasyse Fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.22.0
By upgrading to the pre-release version, v1.22.3 (pre-release), this error got resolved on my end! Note that, if this error occurs, trying to edit configurations would experience the following... Have to open the output for Extension Host to figure out the root cause being Out of memory for Wasm
command 'c_cpp.configurationeditui' not found
