Frequent JavaScript heap out of memory

Describe the bug

Every few minutes the copilot CLI crashes with the following output:

[2525992:0x4f1e6000]  2035407 ms: Mark-Compact 3919.7 (4098.2) -> 3918.2 (4097.4) MB, pooled: 3 MB, 227.10 / 0.00 ms  (average mu = 0.100, current mu = 0.008) allocation failure; scavenge might not succeed

Affected version

GitHub Copilot CLI 1.0.83-5

Steps to reproduce the behavior

1. Initiate some work
2. Wait a few minutes

Expected behavior

don't crash.

Additional context

The CLI is executed on x86_64 Ubuntu/Linux 24.04, fully updated
It is access like Windows Terminal-->ssh-->Linux-->tmux/zsh-->CopilotCLI (no difference when running directly on the linux machine)

Have tried to use NODE_OPTIONS but it is silently ignored.

Ubuntu/Linux 24.04 上の Copilot CLI 1.0.83-5 で作業を開始し、数分待ってクラッシュを再現します。生成された Node.js レポートファイルと、CLI による NODE_OPTIONS の処理から始めます。同じワークロードが JavaScript heap out-of-memory クラッシュで終了しなくなれば完了です。
