Building with GOARCH=386 no longer works

[zyxophoj]

Here's the shortest failing program I can make:

package main
import "go.opentelemetry.io/otel"
func main() {}

Building with GOARCH=386 (e.g. GOPATH=wherever GO111MODULE=off GOARCH=386 test.go ) fails with:

src/go/src/go.opentelemetry.io/auto/sdk/tracer.go:79:38: math.MaxUint32 (untyped int constant 4294967295) overflows int
src/go/src/go.opentelemetry.io/auto/sdk/tracer.go:84:38: math.MaxUint32 (untyped int constant 4294967295) overflows int

It looks like len() returns a signed int, causing min to compare signed ints, and MaxUint32 is too big to be a signed int in 32-bit mode.

This is happening on Ubuntu 22.04.4 with go 1.21.0 and go 1.23.5; I suspect any version of go that supports min will have this problem.

Thank you for your interest in the project. We do not currently support this architecture. If you would like to submit a PR to fix this, and the other build issues for this architecture, we can help review them. However, we do not plan to prioritize this in the near future.

Closing as this is not an issue we currently plan to resolve.
