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

$ go version
go version devel go1.21-d8c9eece28 Mon Jun 5 17:00:46 2023 +0000 linux/amd64

Does this issue reproduce with the latest release?

No

What did you do?

Run the following steps in an environment where cgo compilation fails, for example because pkg-config exits non-zero:

$ curl https://go.dev/play/p/cNL1boxt5tp.go | txtar -extract
$ go mod tidy
$ go list -e -compiled

What did you expect to see?

No panic.

What did you see instead?

panic: runtime error: index out of range [-1]

Trying to build the package with go build fails gracefully:
