Output of emerge --info

I recently upgraded go to 1.21.1 and recompiled all go packages (@golang-rebuild) as recommended by emerge. Now, k3d is broken. It is not (yet) compatible with go 1.21.1 and the dependency should be restricted to something like <1.21.

There is a relevant but somewhat outdated issue: https://github.com/k3d-io/k3d/issues/1118

The error message that k3d prints:

$ k3d
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 go1.21 runtime. If you want to risk it, run with environment variable ASSUME_NO_MOVING_GC_UNSAFE_RISK_IT_WITH="go1.21" set. Notably, if go1.21 adds a moving garbage collector, this program is unsafe to use.

goroutine 1 [running]:
go4.org/unsafe/assume-no-moving-gc.init.0()

Comment 1 Richard 2023-12-12 20:35:28 UTC

I just tested building k3d-5.6.0 using go-1.21.4 and it works and runs fine.

This bug seems to be resolved by the recent bump to 5.6.0 and can be closed.
