I ran the testcases for https://github.com/IBM/fp-go using gotip
gotip test -run ^TestEnv$ .\...What did you see happen?
The test bails out with an internal compiler error:

What did you expect to see?
The same test runs fine with go version go1.22.1 windows/amd64 and go1.20.11
I expect the test also to success for the latest gotip version.
