What version of Go are you using (go version)?

$ go version
go version devel go1.20-13bd6ddbe7 Tue Aug 9 12:18:32 2022 +0000 linux/amd64

Does this issue reproduce with the latest release?

Yes.

What operating system and processor architecture are you using (go env)?

linux/amd64 on Alpine

What did you do?

run all.bash

What did you expect to see?

clean run

What did you see instead?

There appear to be several failures on the linux-amd64-alpine builder related to PIE build mode. Details:

--- FAIL: TestBuildmodePIE (0.00s)

This needs to be looked into. I am guessing that it has something to do with the builder configuration.

Change https://go.dev/cl/422295 mentions this issue: test: skip -buildmode=pie tests on alpine

gopherbot pushed a commit that referenced this issue Aug 9, 2022
Skip a collection of -buildmode=pie tests on alpine, which are
currently failing on the linux-amd64-alpine builder. Once #54354 has
been investigated and resolved we can turn these tests back on.

Updates #54354.

The errors

fork/exec /workdir/tmp/cmd-go-test-4042215474/gotest2288649889/main.exe: no such file or directory

look like the dynamic linker path is wrong?

Maybe worth trying to build a PIE binary and looking at the dynamic linker path.

FWIW, #54306 also has issues in the cgo tests with Alpine, though quite different errors.
