runtime: race detector SIGABRT or SIGSEGV on macOS Monterey

[zchee]

First, I know macOS Monterey is still beta.
But this problem started after Monterey beta 2 21A5268h (beta 1 21A5248p works), and Apple has been released RC2, so posted (share) this issue.
Note that the bellow output is in the macOS Monterey RC2 21A559, real MacBook Pro, not VM.

The issue template generated go bug command with go1.17.2, but occurred in all of the Go versions.

---

What version of Go are you using (go version)?

$ go version
go version go1.17.2 darwin/amd64

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

What did you expect to see?

Pass all testcase with the -race flag.

What did you see instead?

SIGABRT or SIGSEGV.

Note that if no -race flag, passes at least above testcases.

That might be a hint ...?

I have all InstallAssistant.pkg for Monterey betas except RC (Apple will remove past versions in sequence, so it's no longer officially available).
Actually, I've also tested under the VM. So I can provide anything if the Go team wants assembly information, etc.

What is InstallAssistant.pkg: ttp://mrmacintosh.com/macos-12-monterey-full-installer-database-download-directly-from-apple/

Does it work without the race detector?

It may be that the race detector .syso (in src/runtime/race/race_darwin_amd64.syso) needs to be rebuilt.

But if I was a betting man I'd blame the OS, not the syso.
Does running the race detector for a C program work? objective-c/swift?

[cherrymui]

Try setting environment variable MallocNanoZone=0 ?

@zchee are you running natively on an Intel Mac or running on an ARM64 Mac under Rosetta 2? Thanks.

[TwoDCube]

@cherrymui I experienced the same problem on our project (and I was able to reproduce the author's original tests). I'm running natively on an Intel Mac, just upgraded to macOS 12.0.1.

The env var MallocNanoZone=0 solves the problem.

Also yes, without the race detector everything runs fine.

[cherrymui]

@TwoDCube thanks for confirming.

I think this looks like a macOS bug, perhaps in their malloc implementation.

cc @Developer-Ecosystem-Engineering

[Developer-Ecosystem-Engineering]

Thanks @cherrymui, taking a look to see whats up!

[bmhatfield]

A note here that we bumped into this on Monterey and MallocNanoZone=0 or turning off the race detector did the trick. We like the race detector so MallocNanoZone=0 is our current workaround of choice.

[zchee]

@cherrymui fixed MallocNanoZone=0 for now!
and I'm intel, not repro on M1.

[zchee]

@cherrymui I'll try to nvram boot-args using 0, v1 and v2.

[zchee]

@randall77 I was try to rebuild src/runtime/race/race_darwin_amd64.syso with current head of llvm, but same result.

Does running the race detector for a C program work? objective-c/swift?

I didn't try yet.

@cherrymui I tried nanov2_mode=forced nvram boot-args for force using v2 libmalloc, but same result. still need to MallocNanoZone=0. Just FYI.
see also https://github.com/apple-opensource/libmalloc/blob/317.140.5/src/nano_malloc_common.c#L42 (this user(mirroring) maintaining by me. so safe to reference.
