Memory leak continuous ~200MB/s RAM growth when loading large workspace (graphite)

[timon-schelling]

rust-analyzer seems to memory leak when loading the Graphite project in VS Code. Memory usage grows continuously at roughly 200 MB/s after the initial project load (no progress indicator shown in VS Code). On a 64 GB machine the process eventually gets OOM-killed.
Before the regression, the same project stabilized at approximately 4.5 GB after loading and stayed there (I downgraded to 2026-02-02).

To Reproduce

• Clone https://github.com/GraphiteEditor/Graphite
• Open the repository root in VS Code with the rust-analyzer extension enabled
• Wait for the initial project load to complete
• Observe RAM usage in a system monitor, it climbs without bound

Last known good version: 2026-02-02
First observed bad version: 2026-03-16 (haven't tested versions in between, can bisect sometime next week)
Editor: VS Code with the rust-analyzer extension
Workspace: https://github.com/GraphiteEditor/Graphite

rustc version
rustc 1.91.0 (f8297e351 2025-10-28)
Operating system
