Tests failed on go-1.21

Hi,

During refreshing package in Guix I've faced with an issue when rapid starts experiencing unit tests failure when compiling with go-1.21, please see the trace:

Thanks for reporting! Does this happen on current master?

Hi @flyingmutant

It's failing on the latest commit as well 3aa554aaca7a7a3e7c671564c95190542db6fcc4, same issue.

Full test suite is run daily with several versions of Go and 3 operating systems. Here is one of the runs with the version https://github.com/flyingmutant/rapid/commit/3aa554aaca7a7a3e7c671564c95190542db6fcc4. The problem you are seeing is most likely caused by a custom version of Go (with different Unicode tables) or something of that kind.

Hi,

Thank you for explanation.

Which Go version (commit or build type) is used to run the tests in the CI? I'd try to reproduce it.

It might be this: https://launchpad.net/ubuntu/+source/golang-1.21 I tried to build with https://github.com/golang/go/tree/go1.21.5

Oleg.
