[BUG] Errors with `orchestrion go build` when profile guided optimizations are enabled

[jprobinson]

Version of orchestrion

github.com/DataDog/orchestrion v1.4.0

Describe what happened:

When combining orchestrion go build with profile guided optimizations we're noticing compilation errors.

We've added orchestrion via go get -tool so we're executing the build with go tool orchestrion at build time. If we fetch a profile and set it to the default path, we encounter an error:

$ /go/bin/datadog-pgo service:hello-go env:prod apps/hello-go/default.pgo"

$ /usr/local/go/bin/go tool orchestrion go build -o /go/src/github.com/DataDog/my-repo/bin/hello-go github.com/DataDog/my-repo/apps/hello-go"

exit status 1

The "woven" dependency in the error message does not appear to be consistent across attempts.

Describe what you expected:

The compilation completes without error. When a default.pgo file is not included, we see no error.

Steps to reproduce the issue:
At the root of the repository:

import (
        // Ensures `orchestrion` is present in `go.mod` so that builds are repeatable.
        // Do not remove.
        _ "github.com/DataDog/orchestrion" // integration

        _ "gopkg.in/DataDog/dd-trace-go.v1" // integration
)

The main package:

package main

import (
	"fmt"
	"os"
	"os/signal"
	"syscall"
	"time"

	"gopkg.in/DataDog/dd-trace-go.v1/profiler"
)

func main() {
	opts := []profiler.Option{
		profiler.WithAgentAddr(os.Getenv("TRACE_AGENT_URL")),
	}
	if err := profiler.Start(opts...); err != nil {
		fmt.Printf("Error starting profiler: %s", err)
		os.Exit(1)
	}
	defer profiler.Stop()

	exit := make(chan os.Signal, 1)
	signal.Notify(exit, syscall.SIGINT, syscall.SIGTERM)
	for {
		select {
		case <-time.After(10 * time.Second):
			fmt.Println("Hello, Gophers!")
		case <-exit:
			fmt.Println("Exiting...")
			return
		}
	}
}
