Panic when running the binary: "imports assume-no-moving-gc to declare that it assumes a non-moving garbage collector"

[Cavernosa]

After installing all dependencies that were throwing errors, build was apparently successful. Distro is Arch. Go version: 1.19.1 GTK4: 4.8.1

Running the binary gives an error about assume-no-moving-gc:

$ ./gotktrix
panic: Something in this program imports go4.org/unsafe/assume-no-moving-gc to declare that it assumes a non-moving garbage collector, but your version of go4.org/unsafe/assume-no-moving-gc hasn't been updated to assert that it's safe against the go1.19 runtime. If you want to risk it, run with environment variable ASSUME_NO_MOVING_GC_UNSAFE_RISK_IT_WITH=go1.19 set. Notably, if go1.19 adds a moving garbage collector, this program is unsafe to use.

goroutine 1 [running]:
go4.org/unsafe/assume-no-moving-gc.init.0()
        /home/user/.local/share/go/pkg/mod/go4.org/unsafe/assume-no-moving-gc@v0.0.0-20211027215541-db492cf91b37/untested.go:25 +0x1f4

So I did as it said and added the scary environment variable, and to my surprise I got an even scarier output:

$ ASSUME_NO_MOVING_GC_UNSAFE_RISK_IT_WITH=go1.19 ./gotktrix

Don't know if i'm doing something wrong. I tried v0.1.4 instead of latest, same thing. I'm able to build and launch fine from the gotktrix-git package in AUR

Does this use actual latest git commit? If yes, is the one you built of a stable release?

gotktrix has been due for a new release for quite a while now.

[Cavernosa]

Does this use actual latest git commit?

I think so. In the PKGBUILD file it shows the same commit id as the latest one here ("r373.d903553"), seems to be getting from the last commit in this repository.

If yes, is the one you built of a stable release?

As i said, I tried v0.1.4 but it threw the same error (is that what you mean?), i built by invoking this command:

$ go install -v github.com/diamondburned/gotktrix@v0.1.4

[ThatOneCalculator]

I'm getting the same error

[raspbeguy]

Having the same error (but with go1.20).

[diamondburned]

For Go 1.20, we probably need another update to bump this.
