What did you do?

Seems to be happening when doing a go build in alpine docker with 1.21.4 and 1.21.5 so far, hangs forever on builds that only thing that changed was go version. When I move back to 1.20.0, my code builds fine

What did you expect to see?

go build not hang, but compile my code

What did you see instead?

infinite hang

please include a reproducer

Or, if you can't include a reproducer, please terminate the go build command in a way that will produce a stack trace (by sending it SIGQUIT or a similar signal), and post the stack trace here so that we can see where it is getting stuck.

I will try. I can't sigterm it easily, it's running in alpine docker build stage & the code base is large/proprietary. I'll see if I can get a stack trace

This is my mistake, it's not go hanging, it's make in alpine. Sorry for the bad report
