runtime: intermittent startup panics across multiple Go applications on Windows 11

[Whissi]

What did you do?

I regularly run various Go-based applications on Windows 11, most notably kopia and rclone. Both are invoked normally from the command line as part of my daily workflow (kopia is used 1-2 times per day for backups). Most invocations use the official Windows release binaries; one of the traces below comes from a self-compiled kopia build (with only minimal, unrelated changes -- see commit history).

What did you expect to see?

The applications should start up reliably and execute their requested commands without crashing.

What did you see instead?

On rare occasions, the application panics immediately at startup. Across the four traces I have collected, I have seen four distinct symptoms -- but always with the same overall pattern: a fatal crash very early during program startup, at a different code location each time, that does not reproduce on retry. Re-running the exact same command immediately afterwards always succeeds.

The four observed panic types are:

1. runtime error: invalid memory address or nil pointer dereference deep inside application code (kopia index parsing).
2. runtime error: invalid memory address or nil pointer dereference inside an init() function parsing a static constant byte slice (rclone, golang.org/x/crypto/ssh).
3. runtime error: slice bounds out of range [-4:] inside an init() function parsing an embedded protobuf descriptor (kopia → google.golang.org/protobuf → s2a-go).
4. fatal: morestack on g0 -- a runtime invariant violation inside runtime.morestack itself, while running an init() function that parses an embedded protobuf descriptor (kopia → google.golang.org/protobuf → envoyproxy/go-control-plane).

The fourth one is what prompted me to file this issue in the runtime's tracker rather than against any individual application: the crash is in the runtime's own stack-growth path, not in user code.

Frequency

The issue is rare and intermittent. With kopia running 1-2 times a day, I observe such a panic roughly once every ~15 days. I have been observing this pattern across different versions of these tools for at least the past 2 years.

System information

• OS: Microsoft Windows 11 Pro for Workstations, Build 26200.8328 (issue observed across many builds over the past 2+ years)
• CPU: AMD Ryzen Threadripper 3970X (AMD64 Family 23 Model 49 Stepping 0)
• AGESA Version: CastlePeakPI-SP3r3-1.0.0.F (runtime invariant violation inside runtime.morestack happened with 1.0.0.7)
• RAM: 128 GB ECC
• Go versions: the official kopia/rclone binaries are built with whatever Go toolchain those projects ship with at the respective release; the morestack on g0 trace below is from a self-compiled binary using go1.24.5 (visible in the trace).

Could this be a hardware issue?

I have considered this and I'm aware ECC alone does not rule it out:

• The system uses ECC memory and no correctable/uncorrectable errors have been logged.
• I run PassMark MemTest86 Pro (latest version) regularly with no findings.
• I'm aware ECC does not protect CPU caches, registers, the memory controller, or DMA paths, and that all four traces could in principle be explained by a single-bit flip somewhere along those paths.

That said, I'd appreciate the maintainers' read on the traces. The morestack on g0 one in particular looks like something other than ordinary data corruption to me, since it indicates the runtime's own scheduler bookkeeping was in an impossible state, but I'd rather defer to the experts.

Thanks for the report. This does look very similar to #67108: intermittent Windows/amd64 crashes where runtime state, especially around the current G/TLS path, appears corrupted, often during init.

Could you try running the affected commands with GODEBUG=asyncpreemptoff=1 for a while and report whether the crashes stop or change frequency?
