cpptools-srv repeatedly crashes and generates many core files on Remote-SSH (ARM64, Kylin V10, glibc 2.28, VS Code 1.110.0, extension 1.29.1)

[debuger03]

Environment

• VS Code Version: 1.110.0
• C/C++ Extension Version: 1.29.1
• Remote: SSH
• Remote OS and Version: KyLin V10 Linux
• Architecture: ARM64
• glibc: 2.28
• Network: remote host is in an offline / no-internet environment

Bug Summary and Steps to Reproduce

Bug Summary
The C/C++ extension process cpptools-srv crashes repeatedly on the remote host and generates a large number of core files. This quickly fills the disk.

Observed behavior

• Core files are repeatedly generated by:
  /home/<user>/.vscode-server/extensions/ms-vscode.cpptools-1.29.1/bin/cpptools-srv
• gdb on the core shows:
  • Program terminated with signal SIGSEGV, Segmentation fault.
  • top frame:
    msvc::result_t code_model::remove_template_args<wchar_t>(...)
• Reinstalling the extension did not resolve the issue.

Additional context
The remote machine has no outbound internet access. During extension install/update I also see timeout errors to marketplace / microsoft endpoints, for example ETIMEDOUT, but the extension still gets installed. After that, cpptools-srv continues to crash and produce core files.

Request
Please help confirm whether this is a known issue for ARM64 / Kylin V10 / glibc 2.28 / offline Remote-SSH environments, and whether there is a workaround or a version to pin to.
